Here is a good resource that I have just found. Again, because of my background it does lean very heavily on the Broadway stage and show tunes. They are weekly hour shows hosted by Laurence Maslon that have a theme or tangent. The menu is a bit hard to navigate until your figure out the lamppost motif. But once you do, you can sort by performers, writers et al. Lots of creative topics in the archives from getting old in the business to haunted Halloween numbers. If nothing else, it is a great resource for both music and story, free for your listening. I will add the link here, but also add it to our resource links on the side.
