Playing in C Major modulating to the key of G Major.

1-End with a C chord then play Am7 D7 -- IIm7 V7

2-End with a C chord then play Bm7 E7-5 Am7 D7-5
IIIm7 VI7-5 IIm7 V7-5 Notice the chromatic bass line

3-End with a C chord then play Am7 Bm7 Bb13 Am7 Ab7
IIm7 IIIm7 bIII13 Im7 bII13

Or simply use the repeat ending that brings you back to the top,
Transposed to the key you are going to. (In this case G Major)

If you have enough imagination (You can hear the changes) the possibilities are limitless.

Although I do use the transpose button at times I try not to use it because there have been times when I got to the next song and forgot to turn it back.
