I wish I enjoyed singing more. I don't. It has to be done in a small group and I am always elected.
Over the years, I have done lots of singing on national advertising campaigns (Sealtest Milk, Lensecrafters and lots of others), and am invited to sing (and sometimes play) at tributes to people like Beau Diddley, Bing Crosby, Nat King Cole and lots of others with a local Philharmonic.
I don't hate it but enjoy making those who really love to sing sound the best they can sound a lot more than singing myself.
Back-up vocals help. I don't mind them if it make the final production better.
What's sad to be are those who love to sing but don't do a very good job. There are a few here who aren't nearly as good as they think they are.
