Who Sings Hey Hey Hey Hey What's Goin On. I Step Outside I Take A Deep Breath And I Get Real High I Said Hey What's Goin On?

A Disco version was made by D J Miko in the 1990s.  It's on You Tube < DJ Miko - What's Up? www.youtube.com >  
I think this is their only song that made the charts in the US: "What's goin on"

"4 non-blondes" made this song. I think it's called "whats up."
