Well, the other three had topics like this, and Brian looked left out. I love that quote where Brian said "I am in danger of becoming a prisonner of my own hair" and he's certainly known for his hair.
His current "save the world" endeavour is his albatross "Rocky." You can read about it at his site (BrianMay.com for those living under a rock).
So, yeah. Brian's hair.
Brian: Why is it always about my hair? What about what's underneath all that?
Roger: More hair?
