It was on this day in 1970, The Grateful dead played their first concert in the UK at the 2 day Hollywood Rock Festival.
Isn't Hollywood in the U.S.?

This festival was held on a pig farm near Staffordshire, and featured Mungo Jerry, Free, Black Sabbath, Ginger Baker and Traffic, as well as The Grateful Dead.
That must have been a hell of a festival to be at!

Anyway, this is a good time to dig up some good old 'Dead' music, and I found this video the the guys jamming out to 'Hard to Handle' at the Hollywood Rock festival.
