I just sat down at my trusty S-950, selected a style from the Movie & Show section, Movie Ballad, set the tempo, then worked my way through the variations. I used the onboard grand piano and strings, playing the song as I remembered it from the cobwebs of mind from watching the movie. I recorded it using the onboard USB recorder, which precludes any editing, then loaded it into Audacity and converted it to an MP3 file. Piece of cake.

All the best,
Gary
