Funny you mention Jack Black. I just got done watching this... http://www.youtube.com/watch?v=RmU7FshBwgg&feature=related
He had a great voice. Liked the sound but was never a big fan of his overall style. I would have had a concert shirt were it not for my friend getting stabbed three times at the 58 or 86 concert in Houston. Almost killed all for five t-shirts. He was taking them to the car for "Safe Keeping".
Saw Dio last year in Boston with Heaven and Hell, great show just not as long a set as hoped. RIP Dio.
Black Sabbath is my favorite band of all time and it's a shame when an influential member dies like that. He wasn't there all the way through but he left an indelible mark on the legacy that's for sure.
I had planned on going to see them then, but plans fall thru as usual for me. At least I got to see Dio open for Iron Maiden several years back. Was a hella show!
