Due to the release of a Philadelphia International Records box set, Kenny Gamble and Leon Huff are doing promotional interviews.  I caught their interview on NPR's Fresh Air this afternoon and it was well worth listening to.  I really did not know they had their hands in so many hits prior to starting their own label on their home turf in Philly.  Granted, I am a bit biased having lived in the Philadelphia area all my life, but I think these guys are musical geniuses.    

I think Fresh Air archives their shows the following day, so if you get a chance, you should give it a listen.
