How does one make a tune REALLY sound different?

Hi, my little group just recorded Banish
Misfortune. We played it the “normal” way you hear everyone play it…me on whistle,“G” on Harp and “A” filling in the
background on a Hurdy Girdy and probably a
bass track will be added.
Now, we want to do (Planxty)George Bravazon.
Although the tune is different, the Whistle/
Harp playing will make it sound about the
same to a non-musical craft-fair c.d.
buyer.

Does anyone have an idea how to make
“George” sound really different?
Thanks, Lolly

Play it well :wink:
