Who do you prefer? Motley Crew or Kiss?
Motley Crew.  Never did like the glam bands like Kiss.  I'm more the Led Zeppelin type.
Of course. Led Zeppelin helped create the greatest era of Rock n Roll
Yes. Along with AC DC, Deep Purple, and all the other great bands.  Which was your favorite?
Always loved ACDC and ZZ Top
What about Black Sabbath?  Got to love Ozzy!
Ozzy was amazing ... Crazy Train is genius
Yes!  I did get to see ZZ Top and Deep Purple live back in the seventies.  Missed seeing Led Zeppelin. I had tickets, but they cancelled the concert at the last minute.. 
Those two concerts sound amazing. Yeah it's unfortunate that Led Zeppelin hasn't performed since 2007
They are all getting up there in years.  Everyone deserves to take it easy at some point.  Which band do you think was best?
Probably AC/DC. But they were all great. Someday current music will be considered classic.
