I would certainly agree with Bob about Brian Peters being one of the best singer/button box players around.Brian Plays multiple melodeons and anglo concertina (as well as guitar - but not all at the same time you understand;-)) to accompany songs as well as playing the boxes by themselves for tunes. I have a vinyl album of Brians called "Persistance of Memory" which I can record onto MC and send you if you like - provided that my son gets round to fixing my turntable which he borrowed and then broke!!!
He also features on a number of other albums by various artists - notably "The Widows Uniform", a recording of a stage show done using Peter Bellamys adaptations of Rudyard Kipling poems/songs. Speaking of Peter (rest his soul) he is always worth a listen - OK it is anglo concertina rather than melodeon but the principle is still the same (or certainly very similar!)
PM me if you want me to record the stuff as I am not on here every day and the thread may be gone next time.
Come to think of it I will PM this to you, Rick, just in case.
Cheers
