Thanks for commenting on this Auntie. I wrote 90% of this in about 15 minutes right after doing just what it says. I'm glad you asked about who Lenny was. It is typically a man's name and I unconsciously put him in S1 L6. It should be her. I may have been days noticing that had you not drawn my attention to it. I know you like jazz; you can listen to this and Riviera Paradise on You Tube. They are both amazing. From Wikipedia:
"Lenny" is the tenth and final track on the first Stevie Ray Vaughan album Texas Flood. The song is in 4/4 time and notated in the key of E major (but instruments are tuned down a half-step). It is played very slowly and freely, with Vaughan alternating between jazz-inflected chords and solo runs. The style is influenced by Jimi Hendrix ballads like "Little Wing" and "Angel". The song itself was written and named for his wife at the time, Lenora. Vaughan also named one of his guitars "Lenny", which he used to play this song and also "Riviera Paradise". The song was often played at live shows.
