Mills Brothers - Cielito Lindo = Tight Vocal Performance 1943 (40S07)

John, Herbert, Harry and Donald from Piqua are amazing at vocally imitating instruments. The Four Mills Brothers are terrific.
 
"The music and moonlight, the spell of a June night
The charm of an old Spanish setting
Brought romance in all it's glory
The start of a sweet love story"
 
In this Cielito Lindo music video you'll find only one guitar. Can you both see and hear how they keep changing vocal roles?
