This is Joe Cockers cover of 'With a little help from my friends' woodstock 1969

One of the first things you may notice is him being spastic. This isnt the case off stage, he only gets that way when performing. in this video hes high on something(im presuming LSD)

When he first sent in his recordings to play at woodstock, they thought he was black, they were shocked to see he was white when he showed up on stage
