St. John's offers both instrumental and vocal music education as well as a theater program. The vocal program includes two ensembles, the Men's Chorus, a co-curricular ensemble, and the Vocal Ensemble. The instrumental program has three main co-curricular ensembles, the Marching Titans, the Symphonic Band, and the Wind Ensemble. The Instrumental Department has many other extra-curricular groups including the Jazz Ensemble and the Jazz Machine, a basketball pep band, hockey pep band, the Commencement Wind Ensemble and a pit orchestra for St. John's musicals. Each year the high school performs a musical at the Valentine Theater in downtown Toledo. In 2008, the program performed ""Les Misérables"" and was asked to reprise the show as a touring ensemble. In 2011, the program performed "Titanic" and in 2012 "Anything Goes". In 2013 the program will showcase "Monty Python's Spamalot". A fall play is also performed annually by the Campion Hall Players inside the school's McQuade Theater. Productions have ranged from Shakespeare's "Twelfth Night" and "The Taming of the Shrew" to Miller's "The Crucible" and Bradbury's "Fahrenheit 451."
