Great to hear of renewed interest in the "Hennesseys".
Surely the line in verse two should read "In the pubs" rather ther than "And the pubs" ???
Personally I always equated the muffler and the cap with British working men in general and used to see quite a lot of men wearing same even to football matches on Saturday afternoons in winter.
I'm proud too to count myself a friend of both Frank and Dave and I remember well when they came here to Co.Waterford (Home of Frank's ancestors) in Ireland with the third member of their original group Paul Powell (He had arms like a blacksmith, that lad) Their professionalism and musicianship soon earned them commercial acknowledgement.
Frank's songwriting (for one so young when those songs referred to were written) was quite amazing. The song "Farewell to the Rhondda" will always be a favourite of mine, it has a terrific melody and the lyric is so totally evocative of the subject's lives.
