Wishbone Ash - Live Dates. Pilgrimage has some great live bits on it as well.
Blue Oyster Cult - On Your Feet Or On Your Knees
Spirit - Live at The Rainbow.
Slade - Slade Alive. In a Noddy Holder autobiography I read (I know, contains a disturbing anecdote about a glass coffee table and what a German gentleman wanted to pay Noddy to do... can't remember if he wanted him to do it whilst wearing the sparkly hat) he described their sound as all of them soloing at the same time all the time - so it counts.
The Guess Who - Live At The Paramount.
Thin White Rope - The One That Got Away.
Lots of the Groundhogs stuff is basically live in the studio.
