radio plays have alot of potential--no need to do straightones necessarily.
go to
www.ubu.com and do a search
you find stuff like this:
http://www.ubu.com/sound/beckett_bbc.html
from which you can hear a series of beckett radio plays--this is an option that has ben explored much more by german/eastern european radio than english lnaguage radio, for some reason. so check out the other treats that you find there as well.
