Roger and John put on "Events" then picked up the American term "Happenings". There was no particular stage area and the audience was very much part of the show.
Mike joined them and they first performed as The Liverpool, One Fat Lady, All Electric Show with another poet, Adrian Henri, but then settled on The Scaffold threesome.

Their show, a variety of sketches, poems and songs, was very popular with young audiences, especially students, throughout Liverpool and then at the Edinburgh Festival.
They featured on the regional TV series Gazette (for ABC in the Midlands), they had a residency at Peter Cook's Establishment Club and were the resident band on a children's TV show in the late 60s [ITV I'm pretty sure - Magpie?].
In broad terms Mike provided the tunes, Roger the poetry and John the comedy.
Since the 70s Roger McGough has been very active as a poet and children's TV presenter.
Amongst many other things Mike McCartney had a photographic exhibition Liverpool Now and published a children's book Sonny Joe And The Ringdon Rhymes.
John Gorman now lives on a farm in France but has occasionally appeared in films. He was a major contributor to the classic, pioneering Saturday morning TV show TISWAS in the late 70s.
Lily The Pink was No. 1 the following Christmas. The song features Jack Bruce (Cream) and Graham Nash (The Hollies) and a young Elton John (then Reg Dwight) on backing vocals. Mike had to borrow Ringo Starr's bass drum to get the final thump-thump-thump sound right.
Another success was the memorable theme music for BBC's sitcom The Liver Birds.
The group The Liverpool Scene was active in the late 60s and early 70s, featuring Adrian Henri, Andy Roberts and other musicians.
Neil Innes was touring as Neil Innes and Friends in early 1973 and happened to share the bill with The Scaffold one evening. The two acts decided to amalgamate as Gorman, Roberts, Innes, McGough, McGear and Stanshall. Others soon joined.
