I worked in the music business in the 60's and would like to correct a few discrepancies in Hootenanny's post above. Steampacket was actually put together in 1965 not by George Webb but by the ubiquitous Giorgio Gomelsky of Rolling Stones and Yardbirds fame. Rod Stewart was already singing with John Baldry in the Hoochie Coochie Men billed as Long John Baldry and the Hoochie Coochie Men with "Rod the Mod" Stewart, which had just broke up.
George Webb (strongly featured on last nights BBC2 "Jazz Britannia") ran the Malcolm Nixon Agency (who remembers Malcolm Nixon) at the time, with Scots singer, Fiona Duncan (ex.Clyde Valley Stompers). They specialised in managing and booking out R&B groups such as Downliner's Sect, Alex Harvey, Soul Agents, Sheffields, etc. and of course LJB and the Hoochie Coochie Men.
George Webb still runs a lunchtime jazz session (last Sunday in month) at the Erith and Belvedere F.C. H.Q. at Welling, Kent, where if asked, he will regale you with stories of how he discovered Elton John and possibly, how he formed Steampacket, but he does get carried away!
He is still playing remarkably well and it has been known for Long John's old employer, Ken Sims, to be playing trumpet with the band at Welling. The band when Long John sang with them was actually known as the Sims-Wheeler Jazzmen.
