Yeah, wow, I had forgotten about that, Baker, Bruce, Heckstall-Smith.
Actually replace "Bruce" with "Bond": I'm pretty sure Jack had been sacked and re-sacked at knifepoint by that time, and
those bass notes are just Graham's feet. The song was written by Baker, who reportedly used the royalties to buy a car. The bass-guitar-less Graham Bond Organisation line-up was here and occasionally augmented with Nigerian trumpeter Mike Falana, who'd played with the three others and Bruce in the John Burch Octet before their joining Korner (yes, in my first post on the thread,
quod whoever may have missed it videat, I'd forgot to mention Dick was also a member of Blues, Inc.).
Speaking of Nigeria and Ginger Baker, he moved there for six years, opened a recording studio and collaborated with Fela Kuti, and when Paul McCartney flew there to record
Band on the Run (an interesting adventure unto itself, I'm told) one of the tracks was laid down at Baker's.
Speaking of Macca and Wings, not far from sir Paul's Scottish retreat in the Kintyre peninsula lies the tiny and private Sanda Island, which was
owned by Jack Bruce for some time!
À propos of Jack, I'd also forgot to add he (on bass but especially vocals) and John McLaughlin also played together in Carla Bley's jazz opera
Escalator Over the Hill, itself another Who's Who of musicians of disparate provenances: the less-jazzy side included Paul Jones, another Korner alumnus but most of all of Manfred Mann fame (and thus another former bandmate of Bruce, who'd played and sang background vocals on "Pretty Flamingo" before being replaced by Klaus Voormann, already mentioned upthread), a young Linda Ronstadt, and Mothers of Invention keyboard player Don Preston.
(Speaking of Zappa, little need to mention Bruce playing on "Apostrophe’" with Jim Gordon here I guess?)
Speaking of Carla Bley, what does a free jazz pianist have in common with former (John Mayall and) Stones' guitarist Mick Taylor and the Knack drummer Bruce Gary? Why, they all played in the Jack Bruce Band in the mid-Seventies!
A different and earlier band, Jack Bruce & Friends, featured Larry Coryell and Mitch Mitchell, famously drummer for Jimi Hendrix, and before that an employee of Georgie Fame's (he also may or may not have been the drummer Keith Moon claimed to be better than when he auditioned for the Who!), as were in different times (in the former's case obviously) Jon Hiseman and John McLaughlin as mentioned.
Speaking of John, it was through Graham Bond, a sort of Aleister Crowley fanatic, that McLaughlin became interested in the study of the occult, Eastern religion and philosophy - at the time he joined the London Theosophical Society with Big Jim Sullivan (who in turn later on took up the sitar).
Now, the above is mostly (private islands and Nigerian trips excepted maybe) Kevin Bacon stuff and only interesting for fans of the scene; it's there mainly to reiterate that I could
seriously go on for days on end with this stuff!

I'm a fan myself! 
Mick Jagger got his start as the lead singer for the Rolling Stones.
Sting not only sings, but he also plays bass.
Mick and the Stones were the most prominent of Alexis Korner's protégés; as for Sting, some time after realising I could hear some Jack Bruce in Sumner's compositions (in the way both would spice up otherwise straight pop chord progressions with unespected little twists), I came into two bits of info that confirmed me in my guess: in an interview I read Sting put Jack's first published solo album,
Songs for a Tailor, in his 10 desert island albums, and browsing through his autobiography I found out he saw Bruce perform with the Graham Bond Organisation in Newcastle in his early teens/ OH MY GOSH SOMEONE PUT ME DOWN ALREADY.
Rocks come in three varieties: igneous, sedimentary and metamorphic.
And sigged (but allow me a tiny edit), thanks!
