I have first seen Sebastian Lacause in the 200 Broadway revival of ROCKY HORROR PICTURE SHOW in Circle in the Square. I remember it was one of the previews and the show had plenty of technical problems including one of the props getting stuck onstage and the most memorable was when Sebastian’s balls popped out of his skimpy swimsuit. He was very professional and continued his number without tucking in his balls but my eyes haven’t left that swinging ball all through that musical number!
Another shout out to David A for this video of Sebastian at Splash Bar NYC I believe shot 2010 when he reprised his number from Broadway Bares. He still bartends in Splash Bar occasionally. He can be seen in the web series HUSTLING.
