This appears to be the complete show. It's identified on the recording as the first day of a short American tour.
It's possible that this recordingoriginated from Joan McNulty (Pete Shelley's girlfriend at the time). Apparently she taped much of the 1979 and 1980 tours. However, none of the songs from this recording appear on the "Lest We Forget" live release, so perhaps this tape simply came from someone who was at UMass in 1980. The show itself is highly recommended - classic Buzzcocks songs, an energetic set and a known lineage.
