you might mean the NME Pollwinners Concert - here's what nzentgraf.de has:
1968 12th May: Wembley, Empire Pool, 'NME Pollwinners Concert’
- Jumping Jack Flash (MJ/KR)
- Satisfaction (MJ/KR)
i'm not sure it was televized, though - at any rate the footage doesn't seem to have survived.
the David Frost show appearance (november 28th 68)
was televized, of course, but it wasn't JJF, it was SFTD.
"What do you want - what?!"
