Woohoo! My first recommendation.
Bernard Kawka, one time vocalist for the Novi Singers, recorded this little dancefloor filler in 1989. It has a slight Steely Dan/Donald Fagen sound and feel to it, which doesn't usually grab my attention in this way, but this really is a fantastic track. Great arrangements by Bernard too. He's joined by Polish female vocalist Ewa Bem who was in a Novi-esque vocal group in the 70's named Bemibem. I'd never heard of this group before buying the compilation that "Sky's the Limit" is found on. The comp is titled "Holding Hands - Rare Jazz/Fusion Gems From Polish Vaults Vol. 2". It's on the English label "Cosmic Sounds", which must've passed me by because they've been releasing compilations for at least the past 4 years and I hadn't come across them before. The "Holding Hands" comp is really suprisingly good. Every track is a winner.

* P.S. Please excuse the MP3 quality. I wanted to fit as much of it in as I could.
