I've just found an older interview part  with him, after he acted on Dirty Dancing. I don't find the whole interview because this part is embedded in a later interview with Barbara Walters, just before his tragic death. In this little portion he talks about how much he loved his father and he bursts into tears..
 I hope it's ok if i post this : http://www.youtube.com/watch?v=UoQKPycXpVc
