Oh, Rainbow

Oh, Rainbow
 
Oh, rainbow, oh, rainbow,
     How lovely are your colors.
Oh, rainbow, oh, rainbow,
     How lovely are your colors.
Purple, red and orange, too,
     Yellow, green and blue so true.
Oh, rainbow, oh, rainbow,
     How lovely are your colors.
 
by Author Unknown: sung to the same tune as that of, “Oh, Christmas Tree”
