Thought we might see them at Tir Na Nog folk club, but no.

By the way, K.T's Underwater World doesn't go under the harbour, it is all in a large sewage tank!

Well, it WAS a sewage holding tank until we stopped dumping the stuff into the sea. Then it was a large concrete-lined hole with the tide washing in and out, and then K.T. bent up the tunnel and invented the genre.
Impressive when stingrays swim over the tunnel and block out the light!
