Hi there Vincester,
Love "hit the road jack"... I would suggest you either find some Ray Charles songs to match your first tune or just keep it simple and include some 12 bar rock and rollers like "Hound Dog" "Blue Sude shoes" and "All shook up", "whole lotta shakin goin on" which I normally play in the key of (E) but could be played in any key to suit. Think these would link up okay to a tune in (Am) I reckon.
Start and finish with Hit the road jack and even repeat the chorus a couple of times at the end with key changes....usually has a nice affect. Take it up a tone each time....
Now you need to record it and let us here it when your finished yah !!
Best regards,
