Saw this movie in a morning show in 1973 when studying in college.Enjoyed the movie and songs.Wanted to see it again and went to same theatre next day.Lo.The movie had changed and it was Mrs&Mr.55 that was showing.Saw this film also and again enjoyed the movie and music.Since that moment, I have been an admirer of Guru Dutt and staunch fan of OPNayyar.
