Something was off with the sound for both Adele and Barbara-neither seemed in good voice, but the mic needed to be pushed way up in volume. Also, when Seth and Kristin sang at the end, it was hard to hear many of the lyrics. Shirley slayed--OMG! She's 76 years old--go Diva!
Some porn stars make most of their money by traveling to large cities and escorting. Seems to me that this would be a lot to deal with, people's expectations, safety issues, having to "perform". I say pay them lots more for their film work and they will have more personal space/time.
