Bonanza & Son interestingly freaky fact No. 962:

Billy Swan had the job of Janitor at Columbia Recording Studios in Nashville in the mid 60’s which he subsequently passed on to Kris Kristofferson… Even freakier is the fact that during the final week of Billy Swan's two week notice Bob Dylan’s Blonde on Blonde sessions began and Kristofferson’s first week on the job was the 2nd week of said sessions…

Why couldn’t my first job have been a shitty job like that?

By the way check out this video for Swan's very interesting cut of the Elvis hit as the more eagle-eyed of you might spot some interesting characters in his backing band including a high flying Byrd on lead, acoustic guitar as well as a very unlikely English drummer and keyboard player!
