Where's Bap out of Hell by Meat Loaf?

OP's Small Faces link is captioned as "All the clips that count from the 1965 film,Dateline Diamonds."

Two observations:
1) I'd not realised Kiki Dee was that old (though tbf I'd never really thought about it);
2) the audience at the Small Faces gig looks very young -- presumably the producers saved money by asking one of the local schools to send their kids along for an afternoon's filming.

Kamp Krusty theme song - The Simpsons.

Sticking with the Small Faces theme - All Or Muffin is one of my favourites.   

I was trying to think of something by the Rolling Scones but Little Red Toaster is the poor best I can come up with.

This may not be the first, but I think you will all approve of the video:
