ok, magic bus is really simple...
i play it this way in my band. so its probably not the way my hero john plays it, but it fits.
just follow the main guitar riff the whole song.

G------------------------------------------------|
D------------------------------------------------|
A------------------------------------------------|
E--------------4---4-4--4-4-4h6p4----------------|

repeat.


or sometimes, instead of hammering on and pulling off, i slide.

the solo, just play louder, and a bit faster.

not that hard at all.
