There's quite a bit of well documented Bruce takes on the Di'Anno era, but yep, only a handful from the Blaze era:
Iron Maiden (obviously every live album)
Prowler (ARDO, re-recorded in studio)
Charlotte the Harlot (re-recorded in studio)
Killers (Maiden England)
Phantom of the Opera (Live After Death 4th Side)
Wrathchild (everywhere, re-recorded in studio)
Sanctuary (LAD, others)
Remember Tomorrow (ARDO)
Murders in the Rue Morgue (Beast Over Hammersmith)
Another Life (BOH)
Drifter (BOH)
Twilight Zone (Bruce's audition bootleg)
Sign of the Cross (Rock in Rio, Lot

The Clansman (Rock in Rio, Lot

Lord of the Flies (Death on the Road)
Futureal (Single B-side)
Man on the Edge (Single B-side)
I think the 5 Blaze tracks he's done is about as much as you're going to ever get--seems he really only digs Sign and Clansman since he wanted those back on Lot

. And yes, Ullevi needs an official release.
