I didn't know many people in their early 40's had strokes. : )
Dick Clark was a replacement for Tony Mamorella. Tony was a replacement for Bob Horn. The original name of the show was "Bandstand". It was at WFIL studios at 46th and Market Street in Philadelphia. The changes in personnel were due to improprieties by Bob Horn.
I remember hearing Dick Clark was at a Bush Fundraiser back in 2000
Hope this guy gets better
