[Verse 1] In a healthy heart, two pathways reign supreme Right ventricle pumps blue blood through pulmonary stream Left ventricle sends crimson through aortic gate Separate vessels keep the colors straight One hundred percent oxygen to your brain Clean separation, nothing mixed, no strain [Chorus] But when truncus comes to play One vessel steals the show away VSD opens up the wall Mixed blood answers every call Eighty-five percent instead of pure Cyanotic lips, the telltale cure Single trunk, single valve Body's blueprints can't solve [Verse 2] Right side pushes deoxygenated tide Through septal hole where walls divide Left side squeezes oxygenated red Both colors swirl and interblend One enormous vessel takes it all Lungs and body share the call [Chorus] But when truncus comes to play One vessel steals the show away VSD opens up the wall Mixed blood answers every call Eighty-five percent instead of pure Cyanotic lips, the telltale cure Single trunk, single valve Body's blueprints can't solve [Bridge] Normal hearts keep streams apart Truncus blends them from the start Blue and red become light pink Every tissue gets this drink Fingernails and baby's face Show the mixing taking place [Chorus] When truncus comes to play One vessel steals the show away VSD opens up the wall Mixed blood answers every call Eighty-five percent instead of pure Cyanotic lips, the telltale cure Single trunk, single valve Body's blueprints can't solve [Outro] Two becomes one, the mixing's done Partial oxygen for everyone
