Obviously we know Katharine McPhee has stellar vocals…
But girl dominates one of the HARDEST songs ever conceived on the battle field!
The SMASH star lent her patriotic self to Tide's unfurling of a 6,000 square foot American Flag in Bryant Park Tuesday, where she sweetly sang America's national anthem The Star Spangled Banner, 100% live, sans instrumental accompaniment!
Let your American flag fly with Katie's voice to lift it high (above) and then scroll on down below to view snaps of Kat's pre-fourth Summer celebration.
Happy Happy Fourth of July, lovely people!
