SIR Mick Jagger feared he'd never find a long-forgotten song he once recorded with John Lennon - until the late beatle's ex-girlfriend revealed she had saved the recording. The Rolling Stones star almost ditched his plan to include Too Many Cooks (Spoil The Soup), which Lennon produced in the mid-1970s, from his new solo compilation album, because he couldn't find a decent copy. He explains, "I was trying to find the master and I was digging around - one was destroyed in a fire, one was given to a wife in a divorce who threw it out. "We did find a good master - May Pang, who was John's girlfriend at the time, gave me the master."
