Prince - Father's Song (from the film 'Purple Rain') - piano solo

This is a from a beautiful scene in the 80s film 'Purple Rain', starring Prince. In the film, his troubled father plays it on the family piano, though it was recorded on an electric piano by Prince. It's pretty hard to track down - known either as 'Father's Song' or 'Piano Jam' - so I transcribed it myself. The theme comes back in 'Computer Blue'. Here it is, for your enjoyment
