Here's my short version played from a music book-- using the Yamaha E433 keyboard and one of the synth "pad" sounds. It's tricky to get the fingering precisely correct so you'll see me concentrating. If you miss the correct finger, you end up in trouble on a subsequent note. I put the chords in to make it easier to "wing it" and improvise if I need to. Also, it becomes much easier to memorize and improvise on once the chords are known. Maybe I'll try that over coming days. Here it is "straight" for now.
And here's the score.
