Far Out magazine says it was a group called Blue Cheer.

I was just going to mention Blue Cheer.

Hard to say for sure, but I think Blue Cheer started in 1966, and The Who had already released ‘My Generation’ in 1965. The first Blue Cheer album came out in 1968 and included Summertime Blues.

Blue Cheer,

Robert Plant would agree.
