Here's a link to one of a series of videos about the Switchback Longboards' "Kissing Hands and Shaking Babies" tour.
The videos aren't really about a bus, but they do feature one in a way. I think that even if you dislike some of the content it's an interesting and in a way unintentional documentary of the life of a retired skoolie. Just a warning, these videos contain some bad behavior, foul language and general tomfoolery that I'm sure goes along with any sports team on the road, so if you don't have any patience for silly humor don't waste your time on these.
