The Ledge - Need Advice Please :)

I couldn't fit this question into any of the other categories easily, so, I thought this was the best place.

I will be singing again this year at the annual employee recognition event for work. I am playing around with a good song choice, and would like your suggestions on a Mac/Stevie song I could possibly sing.

My first two ideas were:
Gypsy
Rhiannon (Rosebud style, if I can pull it off).

My NON FM/Stevie ideas were:
Barracuda by Heart
Woodstock by Crosby, Stills, and Nash

It's a fun time, no heavy songs would be welcome. During this part of the show, they are usually wanting to drink, and start getting tipsy.

Thanks guys!
