After the news about that 1977 song called Circles featuring Brian on guitar, I must say it is all very strange.
There has not been any word about that collaboration for 26 years!
You know the fan club has got a list of collaborations along with a detailed biography called As It Began.
OK, OK, maybe this rare collaboration track was forgotten to be included on any list, but it was even released as a b-side with no queen fans knowing about it????? how come????
So the song has even been available for years and years (as a B side) and nobody knew (even me) Brian was there?????

This news comes from: Long-Lost QUARTZ Album Featuring TONY IOMMI, OZZY OSBOURNE (and Brian May) is to be Reissued - Jan. 1, 2004
Sanctuary Records will re-issue the debut album from Birmingham heavy metal band QUARTZ in early 2004. Originally issued on Jet Records in 1977, the album was produced by BLACK SABBATH guitarist Tony Iommi and features guest appearances by Ozzy Osbourne and QUEEN guitarist Brian May.
It would not only be the SABBATH duo that featured on the record. Tony's friend Brian May of QUEEN fame was invited down to the recording studio. The man would get to add a splash of that famous hand made guitar onto the track "Circles", once more featuring a certain Mr. Ozzy Osbourne on backing vocals.
"Circles" inexplicably never made the album, only appearing as the B side to the subsequent "Stoking The Fires Of Hell" single.
The Sanctuary re-release features many bonus tracks, including "Circles".
As all stated above this was due to legalities more than any clandestine reason.
Ofcourse, other well known tracks like Sideway Look: "Bullet Proof Heart" or Errol Brown's "This Is Your Time" (recorded with John Deacon) remain unreleased.
It's nopt really a surprise that noone noticed - an obscure B side by a fairly obscure NWOBHM band. Not the sort of thing we all listen to on the off chance of finding Brian on backing tambourine....
