Standard (EADGBE)

 melody is nice. The song is in , with the chord progression I, vi, IV, V. So

 Major, , , , like so:

 This time each year in our hometown

 The county fair comes our way

 Where the folks gather round to be happy and spend their day

And that chord progression is used the entire song. At the very end,"Yeah the big

strong guy knocked the bell in the sky", it just bounces back between G Major and E minor

every two measures.

The guitar lick played occasionally (intro of the song and before verses come in) is the

4th, 3rd,and 2nd of the scale, so:

For bassists (or guitarists too, I guess) that want to walk the bassline and play as

Brian does in the song:

Which is just the standard 1st, 3rd, and 5th of each chord. Doubling each to play it as

8th notes would sound great here.

And that's it! Very simple song, but a fun one nonetheless.
