When you make that trip in Mar., 2020 to see Love Life at Encores, you might want to check out the Paley Center in your spare time. They now have the TV version of Philemon for public viewing.
I just listened to the Philemon cast album CD again this morning. It really is a stunning score, and the very detailed synopsis relates a powerful, moving story.
I plan on seeing Love Life myself and will probably also be making a side trip to the Paley Center to take in Philemon. It would be great if Encores eventually includes this show in an upcoming season of their Off-Center productions (along with the Chodosh-Grael The Streets of New York, the acclaimed '63 off-Broadway musical whose cast recording was recently re-issued on CD).
