I stumbled on this YouTube subsite purely by accident, but I just had to share it here. It's called "Vintage Video Clips" and it has an almost inexhaustible supply of incredible oldies performers at their peak, doing their songs (in many cases live) on old TV variety shows and films of the 60s. 

It would take most of the day to list them all, but here's just a few of what's on the site, all for free: The Beatles, The Animals, Johnny Rivers, Petula Clark, The Rascals, The Searchers, The Four Tops, Gerry & The Pacemakers, The Lovin' Spoonful, Lesley Gore, The Supremes. The Rolling Stones, The Seekers and Herman's Hermits.

There's even a painful video of Neil Sedaka doing the Beatles' "With A Little Help From My Friends" that could induce serious trauma if you watch too much of it. Yikes!

And that's not even a partial list.

There are also vintage acts from the 40s and 50s, and the list was so long, I couldn't actually scroll to the bottom of the page to see them all.
