Its gotta be ,Number One,  Iron Maiden, Newcastle Civic Theatre, 1985. Awesome ! Small gig but unreal.
               or  Neil Young , Syd Ent cent. 1989 ?
               or Hayseed Dixie @ Cambridge Hotel, Newcastle. ( I'll add the date when I'm in the shed & checkin' out the autographed gig poster. Great crowd too. Everyone from Headbangers, punks, rockabillies, senior citizens (lol), mods, etc,etc. top night.No Drama's.
& The Cult @ Newcastle Workers Club 1987 ? ( Before the Earthquake ) They rocked !!
& any Spy V Spy , or The Choirboy's or any of The Angels gigs, At the old Workies &/or The Palais. (RIP).
