Yowzer! Unexpected DNTO piece

Holy last minute, everybody! Just got a call from DNTO yesterday saying they wanted a one-hour piece for this Saturday's show . . . so I'm flipping and trimming my recent UVic lecture and we're going with "Play That Funky Music: The History of the Disc Jockey."
Yep, 60 years of the DJ in pop culture and reality. iIf you've ever wanted to know how those voices on the radio got there in the first place, tune in and find out. No idea exactly what time yet, 'cause we don't actually record it until Friday morning (nothing like a 24-hour turnaround!), but I imagine it'll be either from 3-4pm or 4-5pm this Saturday, April 8. They update the website on Friday, so check then (www.cbc.ca/dnto).
