The Boomtown Rats session mentioned is here: BBC - Radio 1 - Keeping It Peel - 15/05/1978 Boomtown Rats. Recorded at BBC Maida Vale on 15/05/1978, produced by Tony Wilson. It was then broadcast on Peel on the TX (transmission) date. This would fit in with the details quoted, as the Alan Freeman show, in quad, was the following day. So it seems very likely that they broadcast a quad remix of the Peel session from the night before, as was done with other Peel sessions. Alan Freeman - BBC Radio 1 England - 27 May 1978 - BBC Genome. So sadly this does not imply a missing quad album in the record company vaults. It will be four tracks only and if they do still exist they will most likely be in the BBC vaults.
That's very interesting information you have supplied @artwwweb, and most revealing.
So at best the Record Labels , who own the BBC Discrete Quad Masters made from multi's ,would have at a minimum only 3-5 tracks.
Exceptions would be Pink Floyd's -Wish You Were Here , and likely Tull. (maybe 1 or 2 others ).
I always suspected John Peel would have had a go at broadcasting some of the Quad H and HJ . Rather confirms what I read in the past , from a variety of British Mags in that time period.
BTW Alan Freeman states "album tracks" when introducing something non live , without audience.
I still wouldn't mind Dutton Vocalion obtaining those quads , also known as "Tony Wilson Quad Creations".
Oh yes indeed ! ,I'd buy it ....if it only had 4 quad tracks. Also one thing to keep in mind Michael Dutton has mixed in quad some missing tracks in his SACD'S ( I think from multi's ).
I've only heard 2 of the BBC H Quad tracks from The Stranglers broadcast .
I'm guessing there would be 4 originally , which I think was John Peel 's Show.
BTW , the title track "No More Heroes" is one of the better quad mixes I've heard.
You say it was Maida Vale sessions , which I had suspected myself at one time , but yes that's likely what they are.
I recently , about 4 days ago , googled Boomtown Rats At the Beeb , and found nothing for back in the 70's.
But I did manage to catch an interview w/recordings at Maida Vale in 2014 . The only thing was that there was obvious audience in attendance . This I find strange as none of the "sessions albums" I listed have any trace whatsoever of a live audience . Either that changed over the years since the broadcasts or more of those listings are actual albums ? I found that somewhat confusing .
Don't worry though I tend to believe your explanation that they were mixed as you state.(Maida Vale)
Anyway I would hope one day that these Broadcasts of Tony Wilson's Quad Creations receive a spit and polish, so anyone who should like to hear them gets that chance.
Afterall that's what everyone who enjoys quad should have ...as the opportunity to obtain them for their collections.
They are very good quad mixes FWIW .
