I listen to CBSRMT daily, and when I've gone through every single one from 1974 to 1982, I start again. There's one that stands out as not quite having the RMT formula - listen to Ring of Roses. There's just something about this one that sticks out from the rest as not being a RMT show somehow. Not sure if it's the vocal delivery (all the actors sound like they were standing on top of the mike in an echoey room) or the absence of the usual SFX.
Don't get me wrong, I'm not complaining, but when you listen to these shows daily, it's strange to hear something that just doesn't quite fit. Have a listen if you have it, and tell me if you hear it too...
