I downloaded this pre-queen concert here (Onbekend album or The Sink) I think... they played "I'm So Glad" but I cant find this song anywere... could someone post a link???
Í will be so glad!
According to link ( a very reliable source), it's a Cream song.
According to link, it's on The Best Of Cream.
I put the phrase into a search engine and link four took me a Cream page.
Where were you looking?
