Stan sings Drops Of Jupiter by the musical group Train after fleeing from Francine in "Bully for Steve" when she finds out he has been bullying Steve in an effort to toughen him up. His song is interrupted when Francine crashes her car into his.
Stan: Tell me, did you sail across the sun
Did you make it to the milky way
To see the lights all faded
And that heaven is...(Francine crashes into Stan)
