I can confirm that the first 3 tracks are all based on American Militery Marches. I don't know the name of the original song for track01, but the other 2 are both based on the Washington Post March by John philop Sousa. Bass reached bgm 2 may be based on the "charge" bugle call used by the US cavalry as heard in many ammerican Militery themed shows (the sound ideas stock recording may have been taken from the tv series the f-troup, yes, the larrie storch one). home run bgm is the intro to the finalli of William Tell overture by gyekino Roceni. team switch bgm1 is based on the familiar "shave and a haircut, too bits" jingle that was a comin stock ending of many songs in the early 20th century, to the point that Bob singleton himself used it as part of the credits theme for Barney and friends.
