Well you know the range of an accordion don't you Liz?

About 25 yards with a good arm!

We don't have the "busker in the carriage" phenomenon as often here in Melbourne, Aust as it tends to be very much frowned-upon.

A busker coming up and getting 'in your face' in a train carriage here would be about as welcome as a dose of piles. The most likely favourable outcome would be a very quick request to "Go forth and procreate" while the least favourable one would be a knuckle sandwich applied THROUGH the squeezebox!
