That being said it's worth remembering that the Live At Leeds most people know today (and the version that people praise) is mostly an archival release, so I'm unsure if that should count anyway. The original 6 song version is definitely still great but there's not much to it.
Yeah I'd agree with Wings Over America. it captures the full Wings lineup at their peak before they started to fall apart.
Bootlegs don't count. Gotta be actually released.
