We had a pal to come to jam nights. He was a musician but not something for jam night. He played trumpet in the school bands.
Anyway, he learned these lyrics & would come si he could sing it. The guitar guy learned the chords and we started doing it when he showed up.
I played keys on it, but a few times, I'd step away and do the 2nd guitar solo.
Here's my favorite version of it. Much more dense, which I think suits my ear.

... have you heard this lusher version

The Concrete Blond version actually owes quite a bit to the Dominoes' version.
Is that Cocker singing with Santana? Sure sounds like him.

... but Concrete Blonde wasn't a group I followed closely and I am not familiar with her voice though I had seen videos from them on MTV(?), it could actually be one of the Illegals. It's also on their album 'Bloodletting' as a bonus track from an EP.



I don't think that's Cocker.

Concrete Blonde lead vocalist Johnette Napolitano said of the album:

It was pretty miserable. It's not a happy little disc. We had a string of bad luck and [Bloodletting] was the tail end of it. A particularly bad relationship. It had never happened to me until I was 29 years old. I had a hard time getting over it. So, it's not a happy record, but I could do two things: I could make a self-indulgent record, which is what this is, or I could lock up all these songs in a closet and do something that wasn't sincere. This will never happen again, this record.

That is Cocker.
