[Verse]
G         B7              Am
Oh, lord, what a thing to say
B7              Am
What a thing to say
C
Right to Maria
G                    B7             Am
Pears in the winter, Peaches in the spring

Came to me in a dream last night
        B7             Am
Casting shadows in the candlelight
C                Am
Along the cavern walls
    D     G
You call

Oh, oh
