A native of Toronto, Ontario, Canada, Lee Beddis spent his youth with the Peterborough Krescendos, the Canadian Knights, and the Dutch Boy Drum & Bugle Corps. He would later move south to join the ranks of the World Champion Garfield Cadets in order to become part of the now legendary "perfect" percussion line of 1987. After winning his second title in 1990, Lee aged out, swiftly moving into the role of instructor.

Lee's instructing experience began with the Madison Scouts, Star of Indiana, and Phantom Regiment. It was there, in 1996, that Lee helped capture the World Title with his ambitious leadership and musical compositions for The Defiant Heart, an all-Shostakovich program. In 1997, he turned his skills to the rebuilding of the Toledo, Ohio Glassmen. Within a year, his expertise found immediate reward, moving the corps' percussion section into the forefront of World-Class recognition. After the successful 2000 season, he moved to the Crossmen, where he remained until his appointment as Percussion Coordinator of the Madison Scouts. Lee's unique reputation as a program builder prepared him for the role of returning the 2005 and 2006 Madison line to elite status.

In 2007, Lee's unique reputation of building quality percussion programs with success in short periods of time fit in with Carolina Crown's desired level of success. Through five seasons with Carolina Crown, Lee's leadership and team brought the percussion program to within striking distance of being the best percussion section in the world while contributing to the overall success of the corps.

During his time with Carolina Crown, Lee took on the responsibilities of percussion arranging and consulting for the Crossmen in 2011. His leadership and strong advice led the Crossmen back into DCI Finals in 2012 for the first time since 2004, which was the last time Lee led the percussion caption for the corps.

After much evaluation, Lee decided to return to the Madison Scouts in 2012-2014 as Percussion Director, followed by the assisting at The Cadets in 2015, 2016, 2018, and 2019. In 2021, Lee returned to the Crossmen to reestablish the percussion program. He recognized these moves as being a great challenge, and it proved to be successful in building and maintaining these percussion programs at elite status.

Lee's experience at all levels of instruction from tech, to caption head, arranger and percussion coordinator made him the perfect choice to return to The Cadets as Percussion Director and Battery Arranger in 2023 and beyond. He is very much looking forward to contributing his passion and history with The Cadets and sharing the excitement to come “home” and continue to build upon the legacy.

In addition to drum corps experience, Lee is in demand throughout the United States and Canada as a highly regarded judge for Winter Guard International. He started teaching and arranging for WGI groups in 1994 and moved into judging in 1999. Lee proudly endorses high-quality industry names such as Yamaha, Remo, Vic Firth and Zildjian while conducting marching percussion clinics across North America and beyond.
