I try to avoid clickbait—you know, the Internet equivalent of the TV news teaser, "World ends tonight, details at 11"—but this one on Facebook mentioned both "Basel, Switzerland" and "drum corps" in the subtitle, so I succumbed. I was glad I did. (Thanks, BJ.)
The Top Secret Drum Corps founded the now-famous Basel Tattoo in 2006. I enjoyed watching the parade in 2010, though we didn't attend the Tattoo itself, being fully entertained by newborn Joseph.
