I would say your spot on Mr Raffles
I've just taken a listen to my audio recording of the full show from October 74 which includes some excellent live performances from other artists as well as Rebel.I'd forgotten all about the Mike MCgear single Leave it,think he's Paul McCartney's brother?....a great single perfect for the time ,very glam!
It was this Rebel line up that played that short tour in the autumn of 74 culminating with the legendary Rainbow show which was introduced by Kid Jensen who I still listen to these days on Age UK's station The Wireless, funny old world!!!
Thanks to Roualt for the great video of Big Big Deal
