Youâre thinking of two separate midâ1970s performances at the University of Tennesseeâs Alumni Gym (âAlumni Memorial Gymâ), both featuring Nitty Gritty Dirt Band and John Hartfordâthough not on the same bill:
Nitty Gritty Dirt Band at UT Alumni Gym
They performed at the University of Tennesseeâs Alumni Gym on MayâŻ19,âŻ1973. The show was noted as âsolid,â with the band headlining their own concert and described as âwild and exciting.â
They also played again in the spring of 1974 as part of an outdoor show at Circle Park that was moved indoors to Alumni Gym; this performance occurred without member Jimmy and included other acts in that lineup.
John Hartford at UT Alumni Gym
John Hartford (or John Hartford Band) is credited with performing at Alumni Gym in 1972 or 1973, though the exact date is somewhat ambiguousâitâs listed simply as â1972/73.â
If you recall John Hartford opening for or being part of the same evening as Nitty Gritty Dirt Band, the closest alignment would be their show in 1973âHartford possibly performing in the same year, even if not on the exact same date.
