If a 'big act' like Muse or Paul McCartney is playing London then there well may be a reference to the upcoming show on daytime tv. However, the old space-rock bunch, Hawkwind, don't really register on the public or the tv industry radars.
I was in the capital recently, to see Hawkwind, and was pretty surprised to see this on Channel Five.
The Great British Barbershop Boys, doing a brief rendition of an old Bob Calvert song!
Matthew Wright's show is called The Wright Stuff, and so he probably had no problems persuading his producer to allow a snatch of The Right Stuff. Had he wanted Brainstorm, or Sonic Attack, I daresay it would've been a different story! Anyway, Matthew's a big fan of Hawkwind - he even sang on a single they released in 2005 - so it was fun to see him get away with it!
Hawkwind fans were given a heads-up that something Hawk-related would be happening on the show, which is why I tuned in. I usually completely avoid daytime tv.
