I was really into Black Sabbath but heavy guitars can really be very limiting it's a great frequency and it's great fun to listen to but on the other hand musically you can do a lot more without it.
I don't know if there is a gene for comedy but my dad was a very funny man. He just didn't know it. He was a naturally funny character and when my brother and I would laugh at things he said and did he would say 'What do you think is so funny?'
