No Guran you thought you were wrong once, but you were actually right!

Hallo Steve,I tried to play the Duet as it was, but the more I practised the more it started to effect my Anglo playing,so I had to make a decision one system or the other and stayed with the Anglo.The two tunes I was playing on the Duet arranged by Iris Bishop I decided to try and play on the Anglo.My efforts are on Utube "A sin to tell a lie" and "A Nightingale sang in Berkely Square".The Duet was not played for about a year and I decided to convert it.As it was in old concert pitch and requiring very little conversion to Bp/F I changed it to Anglo.As very little alterations were done to the reeds it is possible to convert it back to a Duet,but it is now played regularly,the key being ideal for some songs and hymns.The trombonist who joined me to play them sadly died of cancer,but I still play it but solo.
I would not recommend converting these instruments to anyone, unless you know what you are doing ,it was not an easy job and certainly used up my experiences of tuning and concertina repair work.
