Portaerei

Actively serving Aircraft Carriers of the Marina Militare.
You smug-faced crowds with kindling eye
Who cheer when soldier lads march by,
Sneak home and pray you'll never know
The hell where youth and laughter go.

Who cheer when soldier lads march by,
Sneak home and pray you'll never know
The hell where youth and laughter go.
