Unknown music on a catssette tape please help.

If you haven’t run across this yet...well, if anyone can solve this mystery.
Sounds like late 70s/80s proggy sounding. Figured someone here might know who this is.

I saw this posted on progressive ears and was tempted to post it here. Glad you did. I have no idea who it is but it sounds like mid to late 70's to me. I know it's not them but it sounds a bit like Sweet.
