The one and only thing I've ever been jealous about is anyone who was of age to go to the REAL disco (but not Studio 54, fuck them!) in the 70's-early 80's. Look at all those dynamite afro's! I have one too but save it for when I'm painting my face up like Eric Carr of KISS.
The Jets is one of my all-time favorite groups and still listen to them like their music is currently hot - gotta love how "Cross My Broken Heart" has been given a remixed update much like Def Leppard's "Photograph" a few years ago. Some music will never grow old.
Heathen behavior at its' finest - Soul Train!
