An advert in the paper said that a band were playing in London called Aviator. I did a bit of research and found out that it consisted of Mick Rogers (ex MMEB), Jack Lancaster (of Blodwyn Pig and Marscape fame) John G. Perry (who's history I don't know) and Clive Bunker (Jethro Tull and probably the finest drummer I've ever seen).

This was back in the late 70s. They were brilliant live. They released 2 albums. Aviator and, after Lancaster had left, Turbulence.

Their style is mixed and very difficult to describe but I'm sure any AM listeners will find something on their records they can get into.

As for underrated stuff.

When Tony Kaye left/got kicked out of Yes to make way for Rick Wakeman he formed a band with Dave Foster (who Co Wrote a few Yes songs) called Badger. Their Album "One Live Badger" is well worth a listen in my opinion. It was recorded live (you don't say) at London's Rainbow Theatre and has some great organ sounds on it. Check it out I think you'ld be pleasantly suprised.

PS.
Glad you like "The Good Earth" Jim. Were you able to track down "Solar Fire"?
