Caught a two hour program last night about and staring Pete Seeger and his use of folk music to get people involved in acting upon various societies problems. His basic premise was that music brings people together and together they can accomplish many things. Also made me think about my Baptist background as a kid. Religion can be much more than belief in the supernatural and the Baptists do know how to make and use music for many ends.
If you get a chance, particularly those who are of the post WWII generation the program is definitely worth watching.
