Fairport Convention - Live in Finland 1971

Totally smokin' live set. Richard Thompson and Sandy Denny were already both out of the band but they were still going full steam ahead when this was recorded. Is this a bootleg? I can’t tell. The sound quality is pretty raw and sounds real good and exciting to my ruined ears. Bummer it's only 35 minutes long.
