If you live near the city of Bath, or happen to be visiting, you may like to know that there is currently a project whereby pianos have been deposited in public places for anyone to play. Details can be found in this
local newspaper article.I played some Bach on the bus station piano last Saturday night. My audience was a local tramp (who politely applauded), and a group of young ladies on a night out (one of whom was sick on the pavement - was it that bad?).

You may find more discerning audiences at other locations/times of day
