I managed to see Steely Dan in DC probably about 10 years ago when they were doing entire albums. Walter Fagen's voice wasn't like his youthful self, but he sang the entire 3 hour show and played the rhodes the whole night.
Walter Becker played on a few songs, but he was constantly taking breaks on songs and had a backup guitar player, he died a couple of years later, and then Fagen went.
The also played Kid Charlamagne, and the crowd was on their feet.
