Sunday in the Park interview on XM Radio

I went to the theatre today to buy the cast recording after the Matinee and they were doing an interview with Jenna and Daniel for XM Radio. I stuck around for the hour to watch. They said it was for a show called "Talkback". They spoke for a while and then took audience questions. It was very interesting! They are both very eloquent speakers.

Just curious if anyone knows anything more about this. I don't have XM Radio and know nothing about it, like when it will air and all that stuff. I couldn't find anything about it when I googled it but figured someone may know something.

You can register for a free trial to listen online at the XM Radio website I think. I wonder when this interview is actually scheduled to air.
