The Birthday Party (almost every London gig...)
Nick stole my Guinness on 28/08/1980 - London, Covent Garden, Rock Garden.  Can I have it back by 2014?
Actually written Kieran Gerard (named after my father's father)
Nick Cave and the Bad Seeds Should have been Gerald Kieran (my mother disliked the name Kieran...)
The Moodists Age 0->18 everyone (family, friends, school etc) calls me Gerald (or Gez for short)
Dame Edna Everidge Then university insists I use the name in my birth certificate/passport

The Magic Boomerang Usually it's just too hard to explain why Gez and not Kieran, so I use Kieran

"Hi, my name is Kieran, but all my friends call me Gez."
"Pleased to meet you Kieran."
An Australian physio called Bruce
