This is only the chorus of the song "Sing" by My Chemical Romance. I just used the existing tab and changed it to what I thought was right. These are all barre chords. (You could also play it as open chords: just play the natural of the chord & capo on 1.)

^G#Sing it for the b^D#oys, sing it for the g^E#mirls Every time that you lose it sing it for the wo^C#rld Sing it from the he^G#art, sing it 'til you're n^D#uts Sing it out for the ^E#mones that'll hate your g^C#uts Sing it for the d^G#eaf, sing it for the bl^D#ind Sing about everyone that you left b^A#mehind Sing it for the wo^D#rld, sing it for the w^E#morld
