No, I am familiar with Morton. This was a Rock band in the 70s. Their best hit was “Jelly Roll” from their one album.
They were a one hit wonder, but they did exist on 8 track. Now I can’t even find any references for them at all. And now this artist just made sure we never will by stealing their name.
But they were actually pretty darned good, and deserved much more than what they got.
Was it by chance this band? https://www.youtube.com/watch?v=A5jkVetgtdY
