I was visitig a friend in the spring of 1989 and I heard this song on her personal Wurlitzer. I promised myself that I would remember the name of this band (if not the song itself) so that I could get it for myself. After almost 20 years, I finally found it again! I was remembering the band as Crazy as Anything, not Mental as Anything; and I could never find it until this stroke of luck just now.
Styles have shifted but I still like this song: "Live it Up"!
