"Under the Double Eagle" By John Philip Sousa This one is scored for fun. It's got an easy 'bluegrass' feel to it, but as the piece goes on it begins to fill out first with other percussive instruments, then finally with string ensembles. "Under the Double Eagle" is a tune that will probably stay in your head for quite some time after hearing it. it's a catchy tune, especially put forward in this arrangement. .jmg.
