I too felt too intimidated,to sing at the singers club,this was partly due to seeing Ewan and Peggy at Farningham folk club about 1970.
during the break I bought an LP from them ,which was one of Peggy and Mike Seeger,Peggy was talking to someone else,so I approached Ewan,when he saw the lp,he said with sarcasm,oh you like that sort of thing do you,.I was Nineteen years old,and felt like I was nine and being treated as if I still was at school.
By contrast Dartford, Gravesend, Farningham and most of the london clubs were most welcomomg, so I thought I wont bother with the Singers Club.
