Every now and then I do Google searches for David Wisdom, it was great to find this post. The book looks interesting. Night Lines and Brave New Waves kept me sane (sort of) when our kids were young and learning that night time was for sleeping not playing. I did record stuff from some of the shows, like the Rheostatics session on BNW. But these tapes are most likely long gone. However, I did manage to digitally record almost every episode of Radio on between 2001 and 2003. I am listening to one now and still discovering great stuff on them.
