Recently I had the wonderful experience of hearing the final disc of the set of 9 for this 1928/29 Columbia musical, which must have been one of their very first sound films. I see the IMDb lists it as sound/silent so maybe there were sequences of silent film , but as there clearly were 9 sound discs, I suggest it was a sound/talkie completely. Ted and Mary are a vaudeville act separated by a scheming Vamp who gets annoyed to see Mary turn up in her new show in which she stars with Ted. Mary is booted upstage to anonymity. However by reel 9 Ted knows who he would rather be with and runs to a radio station to call Mary back. The last reel I heard was where Ted goes to a radio station for an interview, his is upset because of leaving his girlfriend in the chorus as he became the star. They have been separated as a singing act but as he croons 'No Love Without You" or something like that, to her across the airways she realizes it is for her and rushes (in 3 mins) to the radio station to end up in his arms, out of the chorus and on their air with him together. Simple and lovely. Does the film still exist? I do not know....or of the other 8 discs... but what I enjoyed for 10 minutes was exciting enough to warrant a search. What turns up in Australia these days would have your head spinning too! The big 16'' disc clearly was labeled "final disc of 9 Columbia Pictures 1928".
