Hi Greg,

The disappointing news is that there appears to be no connection. A search reveal they got their name from a line in a scritti politti song:

"Wet Wet Wet - From the line "his face is wet, wet with tears" taken from the Scritti Politti song Getting Having And Holding. The third Wet was added to distinguish them from such double-headed names as Duran Duran and Talk Talk."
What's in a name

Brian
