I liked the video, I don’t see the problem not letting anyone touch or play the bass, it was the last bass his dad played.
Some people keep locks of hair or other things from their loved ones.
My old dad kept a summer dress my mom wore the day she died 20 years ago (he never took another partner.)
Me, I have no feelings but I certainly wouldn’t belittle people for having them.
I came around late to the soul/Motown scene but Ducks work is a great influence on me now.
