Sir--Although hosted in Scotland and having a distinctly Highlands flavor, the Tattoo is an international event with bands and performers from all over the globe. It has included such disparate performances as Maori warrior dancers, Australian drum lines, Russian Army singers and marching bands of all descriptions, for example. The only real requirement is a military element, not a Scots element, although the Citadel cleverly plays up that connection to their advantage.
As far as getting the FTAB an invitation goes, the Tattoo has to be approached like any other prestigious fora and convinced that we are a good fit. They are unlikely to come looking for us since they have no dearth of interested parties. As the video embedded in the Citadel article points out, the payoff comes from the extensive international exposure and prestige that accrues to their university and corps. Perhaps reaching out to the Tattoo's organizers and inviting a representative over as a guest of the Corps to watch the Band perform this fall might be a good start towards getting an invite.
Anyway, it's a bit galling that the Tattoo's 100 million global TV audience might view the Citadel's unit as the very best military marching band in the U.S., don't you think? V/R--'74
