He and his team of adult directors combed through the applications to put together a band. The final 65 were selected a year ago.
"During that time, we asked them to practice and learn certain music," Pinchock said.
Since they've gathered at the Jamboree, the musicians have put in five to six hours a day with their music, either rehearsing or performing at Jamboree events.
"They are performing four, five, six times a day all over the Jamboree sites," Pinchock explained. "We've done a lot of recognition ceremonies and we're going to start doing what we call flash bands, where we show up at a site, get in concert formation and do a show."
Friday morning, the scout band will board buses and head to Beckley for a noon concert before coming to Charleston. The performances are part of the scouts' community service in West Virginia.
The band will perform in two components here. About 25 members of the band will perform separately as a jazz ensemble before the entire band takes the stage.
Expect some jazz standards and some patriotic tunes, including the National Emblem March and "Stars and Stripes Forever."
" 'Stars and Stripes' has a piccolo solo at the end and we didn't get a piccolo player," Pinchock said. "But we have a fantastic trumpet player and we asked him if he'd do the solo - so he learned it on the piccolo trumpet."
