Imagine when you're looking at the outside of a bus you're looking at the place 1-12 people call home, where they eat, sleep, listen to music, watch TV, keep their clothes, make phone calls, get dressed for shows, pee, fight, fart and f*ck. Most modern buses have two TV lounges, one in front and one in back. The front lounge has a refrigerator that should accommodate vegetarians, macrobiotics, winos, diabetics, and martians. This refrigerator actually accommodates exactly a half a sandwich and a miniature ice cube tray. The bathroom has a sink with non-potable water and a toilet that can only handle urine. Toilet paper goes in the trash can. Dropping a deuce involves a well-timed missive to the bus driver so he can pull over at the next truck stop. The two lounges sandwich the galley, where everybody sleeps (while the driver drives through the night). Bunks line the sides of the bus and are made private by a curtain. The newer buses have individual DVD players in each bunk, which are awesome but serve as a cruel reminder of the 3 foot tall ceiling when you wake from a deep slumber and try to sit upright. There are either 12 bunks (3 atop the other) or 8 (two atop each other) on a convertible bus. The bottom bunk is the noisiest, being closest to the engine, the middle bunk is at the mercy of the above and below inhabitant's activities and the top bunk is the most unstable and more than one unsuspecting soul has been tossed from his bed during a short stop or swerve.
In short, a band ain't living a cushy idle life just because they're on a tour bus. It's a great way to get from place to place but has no privacy and very limited amenities. It takes some getting used to, but it's a small price to pay for getting to play music every night with your peeps!
