There's a huge difference between being a good guest and a good host. High energy, wing it types like David Lee Roth and Robin Williams free wheel wonderfully as guests. The ideal host is more of a Johnny Carson character that only exists to make the guests look good. That means smoothly asking good questions, good ad libbing, and keeping things on track and going.
Dave was at his true pinacle when Van Halen rolled into some town and he did these great local radio interviews that were wild as hell and then he and the band blew the roof off of the venue they played at. I mean classic Van Halen was one big party when they rolled into town and Dave was the master of the party. I mean Van Halen coming to town was bigger than lets say Foreigner coming to town. Van Halen was a party and you were invited to join. Roth on the local radio station made you feel that way. It truley was a unique experience.
Roth now is in his early 50's and it's different times. The magic of the old Van Halen is in the past and will never be again. I wish Dave the best, I'm glad I saw him at his pinnacle and nobody can top him there.
