FWIW Alan Price has the copyright on the Animals version and Eric Burden has been on record that it is to his enduring annoyance that he has to pay Alan Price every time he sings it. And he has to sing it, it is his meal ticket.

When the question of preventing all and sundry copying they put a copyright on the version and (it was claimed) you have to have "one" name attached. Alan got in first. The decision was not unanimous, even at the time. His organ riff is rather memorable though.

Canny lad was Alan.
