Who had the biggest hit with a Beatle cover? no, that can't be right, can it?
hmm...who would that be? joe cocker?
I suppose the answer to that question is Elton's "Lucy in the Sky with Diamonds", which hit #1 in '74. I did a cursory search of other #1's & that's the only Beatles cover I noticed.
And you would be correct. The runners-up:
Sergio Mendes and Brasil '66, "Fool on the Hill" (#6, 1968)
Tiffany, "I Saw Him Standing There" (#7, 1988)
Anne Murray, "You Won't See Me" (#8, 1974)
Earth, Wind & Fire, "Got to Get You Into My Life" (#9, 1978)
Silkie, "You've Got to Hide Your Love Away" (#10, 1965)
Stevie Wonder, "We Can Work It Out" (#13, 1971)
Has Dave ever played Tiffany? Or Anne Murray? Or Sergio Mendes? *sigh*
