razorbacker ... Please see post Number 127 in the SHOW thread where you first posed that question ... where I responded.
I am not going to post the entire response here but PH's #34 hit "Homberg" happened 4 months after WSoP. HOWEVER ... the makeup of the group changed 3 months after WSOP Both a guitar player and a drummer left and were replaced by 2 others.
It's a stretch, I know, but since the group as it existed has only that one hit ...WSoP ... it technically is a one hit wonder!
