Pat,

Just one thing I'll throw in here for consideration is playing some cover songs in styles that are totally different from the originals. They can then be surprising, even while playing a cover, and you can make them your own. The audience will recognize it after 20 or 30 seconds and will hopefully applaud your originality while playing a cover.

Here is an example. I've always liked this song, but now when I want hear it, I play this version on YouTube.

Another cover I just ran across from Hayseed Dixie is this old favorite.

Pick a style and make the song yours.
