Here’s a humorous bit from The Barron Knights who did a bit of The Animals and The Beatles songs during a Christmas medley. http://www.youtube.com/watch?v=NQBes09SLu0 [December 1964] Christmas party https://www.youtube.com/watch?v=OMNssdX_2gk
“The Barron Knights is a British humorous pop group, originally formed in 1959 in Leighton Buzzard, Bedfordshire as The Knights of the Round Table.
Although the Barron Knights undoubtedly had their own style and produced regular ‘beat group’ recordings in their own right, it was their production of humorous parodies that brought them the greatest success. In fact, their catalogue of recordings – although impressive – does not reflect their success as stage entertainers”.
Here’s a recording from ’68 featuring Elton John on Piano: https://www.youtube.com/watch?v=S1r3dQmnQqA
