Oh good lord.
I just listened via podcast to Isaac Hayes on the Adam Carolla Show this morning and wow. I really hope he was high as a kite, because he was almost unintelligible. A caller actually inquired whether or not he had pulled a wake-and-bake. (He claimed to have only smoked pot once in his life. What a shame, because he sounded like he was swimming in a bottle of Benadryl.)
Mumbling, distracted and ... well, it just didn't sound like Shaft to me.
P.S. The podcast engineer still sucks. It's 1:20 in the afternoon and they still haven't uploaded everything.
