Just playing around a bit in Garageband, which I've never used before. Come to a couple of conclusions - I need a better microphone, the ability to play more than two chords and a better voice, but thanks to the miracle of Garageband I produced something that I actual quite like.
Here's me singing Anyone Else But You by The Moldy Peaches (Juno version).
And yeah, that is me singing both the male and female vocals and on twin track guitar.
Oh, and as a bonus, I tackle Britney Spears. Hit Me Baby (One More Time) - Fuzzy Version
