now this will surprise you.as iseem to be known as a concertina player.
Iam a great fan of mjh,Ifirst learned Spike drivers blues,When I was 15 on guitar,and along with [got the blues cant be satisfied] still play it today.I now use mjh guitar style on english trad [have a listen to my version of Rounding the Horn in A ].
The use of the pinky for c9 g6 [and G with flattened third in spike drivers blues].,is interesting,apart from the latter,its the pentatonic major idea.
I am not as good as MJH at it,but I bet hed be bowled over to hear english trad,such as burlington fair,adieu sweet nancy, John Blunt,whip jamboree,Bonny Ship Diamond [melody picked]. http://www.dickmiles.com
ps rounding the horn can be heard as aclip ,on the lancaster maritime festival thread at radio liverpool.
