Coltrane

Coltrane is a friend of Jeremy Johnson in Phineas and Ferb. He is the bassist in Jeremy's band, Jeremy and the Incidentals, and a love interest to Stacy Hirano. He was first seen when he, along with Jeremy and the band's unnamed drummer, performed at the Summer Festival, during which they were briefly transformed into a punk rock version of themselves by Dr. Doofenshmirtz's Ugly-inator in "The Best Lazy Day Ever".

Coltrane was later seen watching Jeremy's TV commercial with him; he then changed the channel to see Candace Flynn on Phineas and Ferb's game show in "Let's Take a Quiz".

Coltrane is also an instructor at the "Summer Rocks!" summer course that Baljeet was enrolled in.
