Gigi (I've been introduced so many interesting musicals or old musical films that I'd never heard before (I wasn't a big fan of musicals) by you guys and have had a great pleasure of watching them recently initially to solve my curiosity but became liking the genre, so thank you!)
Camelot (but not the movie version of it - only the original Broadway Cast recording for me - Richard Burton, Julie Andrews, Robert Goulet) I'm biased, but Camelot is my all time favorite Broadway musical!
