Tom Anderson liked to get his 'The Forty Fiddlers', play ing in the fashion of the string section of an ochestra, with all the bows going up and down in unision.
I remember one Shetland Festival, where Dave Swarbrick was doing a fidle workshop and was asked how to hold and play the fiddle. There were almost audible cries of 'heretic' when he replied that it did not matter and that you should play it where you were most comfortable.
