There are two adult marching bands that I know of . The Get a life marching band of Portland Oregon and the One More Time Around Marching Band .Im not sure from where.I always loved being in marching band.When I heard about adult marching bands I started to watch them play on You tube videos.I encourage everyone who liked band or feels like a old band Geek to check it out.I loved it and it made me have a really good laugh too.
