Blimey, 13 years since the last post to this thread. My Dad has passed away now but the tune lingers on! Here is a better video of me playing it

Waltz of the bells

I send the link to the very helpful and talented Mr Dow (Thanks Nick :-) ), who sent me this is reply. It makes a lot of sense.

Hi Dave,

I found this more than likely to have been taken from a working Gypsy Café band. c. 1935 to 45. This was a money making venture, and the tune may be composed for that purpose. It is rather nice. It probably is not a tune that would have been played privately. Like our own Folk songs the trad. Songs and tunes were more personal. The band may well have perished in the holocaust. 35000 Polish Gypsies were taken. The Waltz of the Bells does not sound especially Polish, it could well be Russian.

Following that and considering the proximity of Bialystok to other countries, I now find it likely that the band could well have been Belarussian, Lithuanian or Ukrainian. The tune sounds like it is from that area anyway. To me anyway!
