I don't know you sister's age, but her musical tastes are pretty diverse, liking both Sinatra and LZ!
If you think about his entire life, Robert Plant has been involved in a huge breadth of musical styles. I'm not sure how he felt about Heart singing STH, as I think he's expressed a since of becoming "tired" with it over the years, but I'm sure he took it as an honor.

It makes her 52-62.
You could get head-banging crazy to Zep (arguably the most cerebral of all rock bands ever). And get mellow to Sinatra. Then get laid to Barry White.
