About Waitin' for the Bus
Waitin' for the Bus opens Tres Hombres (1973): a short, tough shuffle with harmonica and Billy Gibbons's rhythm guitar in E Standard, as every tab shows. It flows straight into Jesus Just Left Chicago, and radio often plays the two as one.
TuneLit measured the song about 4 ¢ sharp on the 1987 CD remix and about 5 ¢ sharp on the 2006 remaster of the original mix, right on the album value (+3.5 ¢, A ≈ 440.9). That rounds to concert pitch: the Tune button sets E Standard at A 440, and an ordinary tuner does the job.
The catch comes at the end of the song. Jesus Just Left Chicago, which follows without a pause, sits about 24 ¢ sharp, some 20 ¢ above this one. If you play along with both, either retune in the gap, or set a compromise reference of about +12 ¢ (A ≈ 443) and accept that each song is a little off. TuneLit's check from the audio agrees that the lowest string is E.
Tip: Tune to E Standard at A 440, and raise the reference about 20 ¢ before Jesus Just Left Chicago starts.
