When I heard my friend sing his version, well, it was so beautiful I had to give it a try. I listened to several versions (including Stevie Wonder, Engelbert, and one sung by a female in the key of F minor). So I chose to use F minor as my key, which is appropriate since F minor is often used to express “Obscure, plaintive, funereal, deepest depression, lament over death and loss, groans of misery, ready to expire, harrowing, melancholic.”
I set up my session players and then recorded it while working out the melody pretty off the cuff. Edited a shorter version, which is where the link goes, although the longer version is still there. Mixed in headphones.
