"Pioneers In Music" broadcast from American radio

[Stranger]

I have a question for Talking Heads fans.

I have found amongst my Talking Heads live recordings "Pioneers In Music" broadcast from American radio, with three tracks they state are 'in concert in 1977'. I'm not sure it's a year later...when they were more assured in their performance (some may disagree, either way I'm just not sure about the recording year).

If anyone knows any details please advise, thanks.
