Re:

When the houselights came up he (Morrissey) was sat in the front row, breaking his balls laughing."

I think that's the translation :) According to the Setanta Site [setantarecords.com] he said:

"Half way through recording Mark decided to do some gigs - “just to get out of the house”. “I did a gig in a small venue in Dublin called The Sugar Club. For a laugh I decided to do my party piece, “Say Hello, Wave Goodbye” accompanied by my very own Pans People action to lyrics routine. When the song was over I looked up and saw Morrissey in the front row breaking his bollix laughing. Surprisingly he offered me some gigs in America and Europe with the highlight being The Albert Hall in London.” "

I don't know why you say goodbye, I say hello.
