Maybe some music industry expert among us with knowledge of typical recording contracts from that time period could answer the question - if Lightfoot recorded the concerts at Massey Hall in the mid 70s - would his record company at the time still own the rights those particular recordings or would the tapes remain the property of Lightfoot?

I guess you could always call him up and ask him if the tapes still exist. Given the response to Neil Young's Massey Hall Cd recorded a couple years previously and the fact that Lightfoot was in his prime - I think there would be more interest in those 70s tapes than ones of concerts from the last couple of years.
