Under the heading..'2nd Favourite Bands' I would have to put Chris Barber's Jazz and Blues Band (vintage 1968-'73) They made an album called Battersea Rain Dance around this time and one of the tracks can be found here :- https://www.youtube.com/watch?v=JyJ3_PiOWG0
It's a very collectable album, because Mr McCartney is amongst the CatCallers at the end; and so, 'Completists' MUST have it. The album features the great John Slaughter on guitar. If you don't know his brilliant blues style, check him out on YouTube.
