'When I'm 64' - This Lennon/McCartney favorite is as charming as ever! Bass primarily has a walking line, while the melody changes hands from the soprano to the tenor. 'Don't Know Why' - A ballad of the 40's in block harmonies. The tempo is medium. 'My Funny Valentine' - Classic ballad by Rodgers and Hart. This jazz arrangement features lush harmonies and many solo lines for all parts.
