I know this is too classical for some people's taste. The audience consisted of quite a lot of churchgoers, so many liked it. We also mixed such tunes with Swing and Pop ones, I compiled some extracts here, third one is Mary's Boy Child in Boney M style (at 1:38, accompaniment made up from scratch on the MoXF sequencer). However, the soprano's voice is a bit classical for such 70s pop music... Everything played on Yamaha MoXF.
