You know you are old when third wave ska is old skool. 
 
Of course, I'm too young for the 1st wave stuff - although I listened to my share of Desmond Decker.  But I was all about Madness, Selector, Specials, The Beat, Bodysnatchers and others crossed over into the Mod scene as well.  I saw all of these band in the early 80's except The Specials.  I'm not sure how I missed them. Madness was at the Whisky and The Go Go's (with a hefty Belinda) opened for them.  Ahhhh youth.
