Friend: I love this series, it fascinates me.
The song that I'm referring to is: "I shot the sheriff" originally from Marley in 1973 and was covered by Clapton in '74. It was his only # 1 on the Hot 100, either with a band or solo. He approached in 1992 with "Tears In Heaven", which reached number 2.
Clapton spoke with Marley to request authorization to record the song.
