I couldn't find the chords or tabs anywhere for Locked Up by Ingrid Michaelson so I just
a video of her and the band playing the song live and the guitars are pretty much 
in the chorus mostly and it just goes like this:

F (133211@1)name="chord_x32010@1">C
G (320003@1)name="chord_x02210@1">Am
G (320003@1)repeat

   F (133211@1)C (x32010@1)      G (320003@1)     Ame|-------------3---------------| (x02210@1)B|----1--------3-------1-------|
