it was a contractual filler. Neil had already started work on the Jazz Singer and I believe ahad already written You Baby, Hello Again and maybe some others but wanted to save those for TJS. I read or heard somewhere in an interview that he had to decide whether to use September Morn or Hello Again for this contractual album release - whichever one did not get used would make it in to TJS. I've always wondered if that "Jazz Time" instrumental type track was originally written with the intention of being for TJS soundtrack?
