Invincible is a number from Act 1, Scene 3 of John Bartlett's musical Gold Star Agency. It is a powerful ballad sung by tenor, Peter,  in which he believes the power of the magic stone has made him invincible. It is approx. 2 mins. 30 in duration and is ideal for a standalone performance, since the words are generic and can be sung out of context of the musical. Compass is E3 to G4. Other compasses available on request.
