Welcome to the 2021-2022 Season of the Ontario Chaffey Community Show Band!  Sadly, our 2020-2021 concert season was cut short due to the Covid-19 pandemic.  But this year we look forward with great excitement to our upcoming concert season.  Please see and our tentative show schedule.  This season will mark 37 years since Jack Mercer came out of retirement to form an alumni band of forty-two musicians.  Currently, the membership of the Ontario Chaffey Community Show Band is comprised of a wide variety of occupations from doctors, lawyers, dentists, mechanics, educators, and other professions.

For over three and one-half decades, the Show Band has been performing one free concert a month for the Greater Ontario Community, bringing in an array of talented guest artists as well as providing musical performances for various city-sponsored events.  The Show Band is directed by Dr. Gabe Petrocelli, esteemed composer, arranger, and conductor, and two assistant conductors:  Mr. David Schaafsma and Mr. Patrick Arnold.

The Show Band continues to grow as we add tremendous new talent to our band.  We feature many of our own musicians as conductors, vocal and instrumental soloists, and also welcome a talented array of guest artists to our programs on a regular basis.

We're excited to start this season on Monday, September 20th with an outdoor concert in the North Quad at Chaffey High School.  The concert theme is appropriately titled "Welcome Back", a tribute to our faithful concertgoers.  The program will feature Concertmaster Chris McAleer, Clarinetist-Singer Sandy McDaniel, and Assistant Director Patrick Arnold.  Other artists featured throughout the season include Martene Craig and her Bell Ringers, renown percussionist and educator Homero Chavez, Rock n' Roll singer of yesteryear Ron Ellington Shy, concert pianist Dr. Maria Perez, and others.

The Ontario Chaffey Show Band relies on the generous donations of sponsors and financial support from the City of Ontario to help keep our programs running.  Additionally, a non-profit organization called "The Friends of the Ontario Chaffey Community Show Band" helps to provide assistance to the Show Band.  If you enjoy the Show Band performances, please consider making a tax-deductible and secure payment via our PayPal account, conveniently located on left side of our website.  Or, mail your donation to: Friends of the OCCSB at P/O Box 1512 Ontario, CA 91762.  Your donation helps to keep music alive in the community!
