Name that tune

Nothing much on tv so C decided to “strum”
It was the turn of his ukelele tonight.

He was figuring out something we had listened to on a tv concert last night.

Played by a renowned uke player known for his rock n roll & skiffle, and his spikey hair ;-)

The tune was written way back in 1942 and was a favourite of George Harrison’s …. and this chap played it at Georges tribute concert after he passed away…… so name the tune :;-) !!!
