Interestingly it was John Lennon who introduced Cilla to Epstein and persuaded him to sign her, and not McCartney.
Well John Lennon wasn't the 'working class hero' everyone made him out to be either. As I said before ... I'm not THAT fond of McCartney - but in their partnership (apart from just one or two songs) it was McCartney's that were my favourites.
In fact - the best thing about John Lennon was Yoko Ono! She's done more for Liverpool than Lennon ever did.
