With the fun loving quartet, Rusty Pipes you just never know what they have up their sleeve next. What they do mean is that all men that can carry a tune should find their way to the Bangor Parks and Rec Building at 647 main St. Bangor Main. This is the location where at 7:00 PM on October 6, 2014 and for the next six weeks the Mainely Music chorus kicks off their Learn to Sing program.. The Rusty Pipes would love to teach you some of their favorite tags (short endings of songs with the best chords) and show you the fun of singing barbershop harmony.. Rember, the Rusty Pipes Mean Business when it comes to singing barbershop.
