AMIGO'S GUITAR
(John D. Loudermilk, Roy Botkin, Kitty Wells)
« © '60 Acuff-Rose Music »

Tonight they're singing in the villas.
Tomorrow you'll be gone so far.
Hold me close and say you love me
While Amigo plays his blue guitar.

CHORUS: Ay-ay, ay-ay, the moon is lonely.
Tomorrow I'll wonder where you are.
Mañana morning, my darling,
I'll be blue as Amigo's guitar.

They've hushed the singing in the villas.
All is quiet beneath the stars.
Amigo plays Hasta Luego
Upon his lonely blue guitar. CHORUS
