Here's a few notes contributed by Jeffery Gill:

I played guitar on that CD and was actually the fifth member. I left Rare Air just prior to the recording of Space Piper to pursue a career in aviation (although I went on the road with them a few more times, as well as playing on the recording). Thus my writing credits did not make it on the back of the CD. 

Rare Air started in the late seventies as Na Cabarfeidh. At that time, they were strictly a celtic folk music group. They were lead by Grier Coppins and Pat O'Gorman, whom more or less, were prodigies of the Highland Bagpipes and an array of other 'traditional instruments'. Soon they became quite popular and were touring the world. They released one album under that name and the following five under their new name Rare Air. 

Rare Air were relatively big in the Southern States, especially North
Carolina. In 1989, two of the original members left the band. I was acquainted with Pat and Grier, as I lead Grier's wife, Sara Craig's band. Moreover, I was all over Toronto during that time playing with everyone. They called me, we played together and I joined. I soon called my friend Rich Greenspoon, a well known jazz drummer and he joined. Christian Frappier was a young jazz player, fresh out of Berkley, actively looking for work in Toronto.

We were on the road for two years and had a great time. We played every type of venue you could think of from Jazz festivals to Universities.

Rare Air is no more. They dissolved the year after this CD was released.

I'm now a captain of a transport aircraft in the frozen Canadian north. Grier has a band in Toronto called Taxi Chain and owns a well known bar. Rich produces music and gigs steadily in Toronto. Christian is in Montreal playing with 'the who's who' of French Canadian music and Pat still tours the USA and Canada. The artist, David Scott, lives in Toronto and paints. He has his most recent work hanging at the Becket Gallery in Toronto.

And here's bit more info provided by Doug McClement:

The Space Piper album was recorded at Comfort Sound in Toronto. I owned the studio at that time. I engineered the "Na Caberfaidh" album and the first Rare Air album. I believe Space Piper was engineered by Andrew St. George,during midnight till dawn sessions. Band leader Grier Coppins met his wife, Sara Craig at the studio, where she was an apprentice engineer at the time. She went on to do several solo albums that were reasonably successful in Canada, sounding a bit like Kate Bush.
