we are/were talking about performers in folk clubs being interrupted during the introduction of songs ON ONE OCCASION this happened at MT CLUB, so your post is no defence of Bobs behaviour at the MT club, in fact it illustrates that his behaviour is possibly pre meditated and deliberate which makes it worse.
However I do think Bob dersves an EFDSS gold medal for involvement in the uk folk revival.
Mike, IMO.the Kennedy incident is a red herring he was not singning ata folk club or introducing a song which is what happened to Roisin White, no performer should be interrupted in a boorish way by Bob Davenport or anyone else.
