Christoph, I do not agree. Boy Scouts is an international movement started in England 100 years ago. Girl Scouts is an international movement started in the United States just a few years after Boy Scouts got started.
While it is true that Boy Scouts and Girl Scouts is popular in the United States, it would be a mistake to characterize them as American traditions.
The World Scouting headquarters is in Geneva, Switzerland.

I was involved in the Cub Scouts and the Boy Scouts between the ages of 8 and 16, in Atlanta Georgia. Now I am 41; last year I was Scoutmaster of a troop composed entirely of Spanish-speaking boys from Central and South America.
Singing is an important Scout tradition. However this is usually a capella around a campfire at night and not in a studio with GarageBand loops.
Here are a few German Boy Scout songs:

Wir wollen zu Land ausfahren
G C G D7 G
Wir wollen zu Land ausfahren, wohl über die Fluren weit,
C D7 G D7 G
aufwärts zu den klaren Gipfeln der Einsamkeit.
C
Wollen lauschen, woher der Sturmwind braust,
G
wolln schauen, was hinter den Bergen haust
C
Und wie die Welt so weit
G D7 G
Und wie die Welt so weit.
