Part way though the song there is a breakdown where Smithers is required to play a guitar solo and this, coupled with the comedy of the actual song, makes it the ultimate WAV file. Yours to own for...absolutely nothing! Download it now! It's FREE!!
The one drawback to this file is that it's quite large (and I've zipped it) but I did record it at high quality so it's truly worth it. I actually have managed to compress it from it's original size which was almost 20MB!
