DR DRUXY - I have seen all of those movies you mention - though some NOT in a long time. SHE'S WORKING HER WAY THROUGH COLLEGE has a great pedigree from the original material.....but I like SHE'S BACK ON BROADWAY a lot better, Miss Mayo has a stronger leading man in Steve Cochran than Ronald Reagan....although Gene Nelson's dancing in both films helps a lot.
Okay, based on your recommendation, I've ordered
SHE'S BACK ON BROADWAY, so if I don't like it, it's on you.

Also, since Kathryn Grayson (and Merv Griffin) is in it, I ordered
SO THIS IS LOVE. Never seen that one either.
My birthday is this month and WHV has given me a 1 month 20% off certificate, so I might as well take advantage of it.
