YAY! I've requested this a while ago and it's on Rock Band 3.
Being that it is part of the Valentines-lovey-dovey-duet crap, its vocals are really the main point of the song.
They're not the most challenging vocal parts to learn, but still incredibly fun to play together. And it might be more popular than you think!
Lead takes Hillary's part, Harmony 1 takes Charles's part (including his verse) and Harmony 2 is Dave's part, which is only seen a couple of times.
