My BB KING archives vol 2, Nice 1979 july 6, 9 and xx, J Winter on last track, FM master, FLAC

This Vol 2 is from Nice jazz festival july 1979 (France Inter and France Musique FM broadcasts).
Three sets are feeding this torrent: july 6, 9 and july unknown.
When more than one version of a tune is provided, be sure i checked the music : they are all different takes.
And the surprise from my basement : Johnny Winter played that 1979 festival and he's here for a song with BB and the band.
