THE glam bassist.
Although I think he didn't actually play on the record, just mimed for TOTP
But he's in the band for Marc's last TV series.
He didn't just play on glam records though, Herb was in demand session bassman all over the first-half-70s shop.
Check out this amazing performance
Less salubriously, he wrote this monstrosity with Kenny Pickett
There is also this questionable song, as later interpolated by the Happy Mondays (and sung by Alan Partridge in one of his series, in an idle, mooching around sort of way).
I mean, they meant well, I'm sure.
At any rate, Herbie didn't write it, so that's okay.
Herbie was in a heavy rock band called Rumpelstiltskin.
And a blues-jazz collective alongside Alexis Korner, called Collective Consciousness Society - aka CCS.
The latter's version of "Whole Lotta Love" was the Top of the Pops intro theme when I was a kid.
And post-glam, as Phil points out in the comments, he was a member of Sky - a classical rock supergroop also including Francis Monkman ex-Curved Air and the dude who did the triffic snazzy OST to The Long Good Friday.
Herbie Flowers also put out a solo album, Plant Life.
And another one called Potty.
Herbie Flowers - the name is quite close the gangster boss in Performance, Harry Flowers - was also adept at playing the tuba. He did that as a bandsman in the RAF, during which he time he also picked up double bass.
Before he got involved in rock, he had been in trad jazz bands, then a more modern jazz band, and then switched to electric bass and started becoming an in-demand session man.
But let's remember Mr. Herbie Flowers this way
