Another I heard first in my sister's collection. I'm 100% certain I was interested because of the cover, not the musicians.*
But it's Cream plus Steve Winwood. Lots of good stuff on it, but this song is what pulled me in:
In the Presence of the Lord has gotten a lot of airplay in the past year or so around where I live. I'm not sure why, but I'll take it for whatever reason.
By the way, check out this cool version - Steven Winwood and Tom Petty, live.
* That's how I heard The Guess Who the first time - they had a cartoon album cover with them as hockey players with the Stanley Cup. So I checked it out. Blind Faith was a better discovery.
