....at the Annual Liverpool Beatles Fan's Convention , at the Adelphi Hotel . A member of the audience asks Bob to do his old 'Cavern Introduction' ...but he substitutes Allan's name instead of saying The Beatles ! When Paul McCartney played The Cavern in December 1999 , he wanted Bob to to this introduction too ...but Bob wasn't feeling too well after a few too many drinks . I was looking for the original camcorder tape for this clip ...but it seems I reused it for my 2 trips to London where I filmed George at Ravi Shankar's annual recital at the Barbican Theatre ! I met George outside in July 1998 and gave him some books about Old Liverpool , in return for an autograph.
