Scroll down for video +7 +7 Rita Coolidge (left) claimed that she actually penned part of Eric Clapton's (right) famous song ‘Layla’ – and did not get the credit for it Coolidge claims that when she asked Clapton’s manager, the late Robert Stigwood, for a credit he told her to get lost and said: ‘You’re a girl singer - what are you going to do?’ In her autobiography Coolidge writes: ‘I think it’s time everyone knew that it (Layla) also has a mother.’ Layla has become one of Clapton’s greatest anthems and was ranked 27th on the Rolling Stone list of 500 Greatest Songs of All Time. The official history of the song is that it was written by by Clapton when he was lead singer of Derek and the Dominos with the help of Jim Gordon, the drummer with Crosby, Stills, Nash & Young. According to rock lore, Layla was Clapton’s declaration of undying love to Pattie Boyd who at the time was married to his best friend, Beatle George Harrison. Coolidge, 70, who later won two Grammy Awards for her own songs, and penned James Bond theme All Time High for Octopussy, says that before she became famous she was a backing singer for Crosby, Stills, Nash & Young. +7 In her autobiography Coolidge writes: ‘I think it’s time everyone knew that it (Layla) also has a mother’ One day she and Gordon wrote a song from a riff in Gordon’s head; she added chords and brought together what she calls ‘his melody and my sweet counter melody’. The result was a song called ‘Time (Don’t let the World Get in Our Way)’ which they recorded onto a demo, the book says. Soon after they were on tour and met Clapton in London. Coolidge writes: ‘We played the song for Eric Clapton when we were in England. ‘I remember clearly sitting at the piano at Olympic Studios while Eric listened to me play it all the way through. ‘Jim and I left a taped cassette of the demo with Eric, hoping of course, that he might cover it. Nothing came of it and I largely forgot about it’. A year later, Coolidge was doing a photoshoot for her first album when she turned on the radio and heard Layla for the first time. Coolidge writes that she screamed out: ‘That’s my music! That’s my music!’ She writes: ‘I was infuriated. What they had clearly done was take the song Jim and I had written, jettisoned the lyrics, and tacked it to the end of Eric’s song. ‘It was almost the same as the arrangement’. +7 According to rock lore, Layla was Clapton’s declaration of undying love to Pattie Boyd who at the time was married to his best friend, Beatle George Harrison (above, with Boyd) +7 Coolidge claims that when she asked Clapton’s manager, the late Robert Stigwood (pictured second from left, with The Bee Gees) for a credit he told her: ‘You’re a girl singer - what are you going to do?’ Coolidge, whose later hits included ‘Higher and Higher’ and ‘We’re All Alone Now’, tried to approach Stigwood to get a credit but was given the brush off. Recounting the conversation, she claims that he told her: ‘You’re going to go up against Stiggy? ‘The Robert Stigwood Organization? Who do you think you are? You’re a girl singer - what are you going to do?’ Coolidge says that there is ‘no way’ that Gordon - who later developed schizophrenia, stabbed his mother to death and remains in prison - could have forgotten that they wrote the song together. She writes: ‘And, frankly, I don’t think Eric could have, either.’ Coolidge talks about her unhappy relationship with Gordon, who she says beat her up one night whilst on tour with Joe Cocker, In the memoir she writes that he ‘hit me so hard that I was lifted off the floor and slammed against the wall on the other side of the hallway’. She claims that she ‘literally went flying’ and was knocked out but whilst she lay on the floor Gordon went back into their hotel room - as if nothing had happened. +7 Coolidge later married Kris Kristofferson (pictured, performing together in 1976) who she met on a flight from LA to Memphis in 1971 +7 Coolidge describes Kristofferson (together in 1979) as a ‘heavy drinker’ who could ‘not be counted upon to be faithful’ Coolidge later married Kris Kristofferson who she met on a flight from LA to Memphis in 1971. They had such a strong connection with that they decided on the name for their first child within an hour of meeting each other. She describes him as a ‘heavy drinker’ who could ‘not be counted upon to be faithful’ and was paranoid and controlling. By the end of the decade he was drinking a quart of vodka per day and would offer crowds their money back for his terrible shows; she left him in 1979. Years later the humiliation continued and women would walk up to her and say: ‘Now that you and Kris are divorced, you probably don’t care. But he and I were together - could you tell him I say hi’. Coolidge writes: ‘You have no idea how many women are so insensitive to their participation in the demise of a couple’. Nobody for Clapton was available for comment last night.
