Jim,

The first line of your reply misquotes me. Check your fourth word in.

It's true that Colyer was in at the beginning of the skiffle craze. He and a couple of members of his band would do a few numbers as a trio/quartet doing American blues and folk songs. When Colyer was ejected from the co-operative band Chris Barber resumed leadership they carried on the tradition. Anthony "Lonnie" Donegan continued with Chris as banjo and guitar player. A "throwaway" unplanned recording became a pop hit in 1956 and things took off from there.

Re your statement:
"The Short Lived 'Ramblers' group was an aberration and had nothing to do with the skiffle movement"

Can I refer you to the Skiffle Album by Alan Lomax and the Ramblers.The group included Lomax, McColl, Peggy Seeger and Shirley Collins. You state it had nothing to do with the skiffle movement ???
This group recorded in 1957. As I suggested in a post above this might just be an example of jumping on the band wagon.
