They've now played 20/20 four times.
The first went fine (it was a week late though, due to a scheduling problem) Then two weeks in a row the same episode (number two) played, also due a to a scheduling f***up. Today Episode 3 played fine.
So I don't know about three weeks. I'm meeting Spliff this week though, so can iron out any problems.
And if he thinks he can get away without paying me...
