Including one on SP and another on Contraction and Convergence, a suggestion submitted for consideration by SP Adopters.

Problems with audio files

Apologies to anyone who is having difficulty accessing audio streams. This is due to problems with major maintenance at the host.

You can still hear the streams on the rolling SL-SPAG Radio station. See the links at the side.
