What's bukkake in Welsh

Bryn Terfel is having a concert at Carnegie Hall on September 16, dubbed a "Celtic celebration" and featuring, get this, a "400 Male-Voice Choir from 8 Countries." 400 men (and perhaps some confused dykes) on stage?? A little poking around yields the following list of choir participants:

Comrades Male Choir [Wales]
Burlington Welsh Male Choir [Canada]
Donaghadee Male Choir [Ireland]
Toronto Welsh Male Choir [Canada]
Maesteg Gleemen Choir [Wales]
Bristol Male Choir [UK]
Montreal Welsh Male Choir [Canada]
Metropolitan Male Choir of Southern Australia
Saengerfest Choir [USA]
Canberra Male Choir [Australia]

Sieglinde counts only 5 to 6 countries (depending on how seriously you take "Wales"), but whatever, you get the idea. Anyway, according to one deeply placed source, a big orgy is scheduled right after the concert at Barracuda in Chelsea, though things may get started during the encores on stage. Hurry, buy your tickets today.
