Wow. He dedicates the song to Glenn Frey, starts Peaceful Easy Feeling and then looks at a girl offstage and she comes and escorts him off. He looked like he was about to pass out.
It doesn’t look completely unexpected. Could be dehydration or almost anything that makes one woozy or some ongoing medical situation. Dunno. Rest up Don.
That’s what I thought as well (Peaceful Easy Feeling), but it also sounded like it could be Tequila Sunrise.
