I haven't played this for about 50 years when I was playing at 'The Old Blue Last' in Shoreditch, with my band Dry Ice. This was a significant song in the early 1970's it sounded so fresh, so original, it's hard to explain unless you were around at that time. Not too many accordion versions on youtube so here is my attempt. It's a 'Frisco' accordion not too many of those about either - love it, a joy to play.
