Michael Henrichsen spent two years persuading the British rock icon to play his party, and it paid off Friday at the packed Showbox SoDo club.
Idol guitarist Steve Stevens played him 'Happy Birthday' in the middle of a solo. Then Idol called Henrichsen onto the stage for a rendition of the song.
Henrichsen's '80s cover band opened for the show.
Idol says Henrichsen's effort stood out from other fan requests because his campaign involved four “Billy Idol Aid” charity concerts that raised $13,000 for the Northwest Harvest food bank and the American Red Cross.
Idol says playing Henrichsen's party in Seattle might help fans see another side of him.
