I actually had this requested of me for the first time last weekend. I recorded my voice over demo in LA and I was somehow brave enough to include a snippet of 'song style vocals'. I wrote parody lyrics to "My Favorite Things". It went a little somethin' like this:
New shoes and ice cream and yard sales and cocktails
Long baths and handbags and good times with gal pals
Men who will bow as I walk down the street
These are a few of my favorite things.
When my job sucks
When my date's late
When I break a nail
I simply remember my favorite things
And then I don't feel insane.
