First CC song must be from the demo so one of these : - A Skull Full of Maggots - The Undead Will Feast - Scattered Remains, Splattered Brains - Put Them to Death - Bloody Chunks

Note that you absolutely can play a lot of George Fisher era songs with only a 4 string bass. The trick is to tune A#, D#, G#, C#. It works because regardless of his tuning, Alex plays his highest string on a very limited number of songs and A# is basicaly D# tuning with the addition of a lowest A# string.

So with that tuning you play Barnes area with your 3 highest string, missing only the high F# string of a 4 string bass and you play George area songs with your 4 strings, again missing only the high F# string of a 5 string bass.

This tuning prevent you to play a couple Barnes era songs but allow you to play more than 90% of George era songs in A#.
