I didn't care for Heart when I was teen but I have really become a fan as I "matured". I had a chance to see the Wilson sisters by them selves and acoustic a couple of years back. I should have gone.
I have seen video that was not too old and Howard was still with them. They may get together from time to time. You are right, they are pretty good with him.
I love the B-52's. It was my first live concert ever and that was a million years ago. I heard that they are recording a new CD... should be interesting.
