I mentioned Cleveland because he was the type of artist who transcended his genre. How many rock & rollers have been turned on to the blues largely because of him? Hopefully, he has provided for something in his will....otherwise, yeah, somebody's going to get a lot of money for her.
I find it impossible to sing while playing lead so I hear you. It's a lot easier if you're playing rhythm though. My son has an Ibanez that is very similar to Lucille. He's not much of a blues player though so he doesn't pick it up very often but it sure looks good hanging on his wall!
I think he's in the Rock Hall...I forgot, I've only been once, and to be honest, I was disappointed. I don't think it's a matter of rockers being turned on to the blues, so much as, that's what they grew up listening to, because of their parents, and when they formed bands in high school, and played at dances, and parties, that's what they played. Then, as they grew and matured as musicians...blah, blah. You know the rest. It's all connected, without this, you wouldn't have that, and so forth. Every generation of kids forming garage bands, thinks their idols and influences invented what they hear...then mom or dad slaps them upside the head with a record or tape from THEIR youth, and brings them back down to the cold hard fact, that it was done years ago, and THAT'S why YOU want to do it!
