"Perhaps it's because the Pythons are based in England, and they perhaps have a larger fan base in England. "
This was my thought as well.
"Just because a song might be bouncy or singable, it doesn't mean people should go ahead and join, as it detracts from the performance. It isn't a concert which encourages audience participation. "
I think it depends on the show. Chitty, for example -- at least in London -- audience "participation" became almost the norm by the time the original cast left. In fact, the cast seemed to "feed" off the reactions, to even greater effect.
