I'm another 1991 fan, and ARLO was the first album I bought rather than taped off a mate, loved it when it came out and played it non stop for months. ARDO not so much, I remember thinking how wimpy the riff from Two Minutes to Midnight sounded, how sloppy Where Eagles Dare was and how vastly inferior the songs were to the versions on Live After Death. But the version of Hallowed on it, is still for me the definitive version. Haven't listened to either in a long time though. I think that has a lot to do with the fact that the songs are mixed and matched from different gigs and are shoe horned into one album being before LAD and the other after it. It makes them feel not like a real album.
