MARY POPPINS was the only movie my parents took me to see in theatres 3 times!!! (About 6 months between each time)  I loved the film, but they must have as well, otherwise twice would have been the maximum (anything more than once was rare).

This made it all the more strange that, despite my going to a Catholic school for 4 years, we NEVER went to see THE SOUND OF MUSIC until a reissue in the 70's. And then we went 3 reissues in a row (that thing was very popular).
