I play this one in A

  A
  If you ever feel lonesome

  And you're down in San Anton'

  E                                       D     
  Beg, steal, or borrow two nickles or a dime
  
                                  G
  And call me on the phone.
  
  A
  And I'll meet you at Alamo Mission,

  And we can say our prayers.

  As we kneel there.
  
  Chorus
  
  G                     D
  In the moonlight
  
       G                 D
  At midnight
  
            G               D                      A
  In the moonlight, midnight, moonlight.

Definitely pick up Old and In the Way, if you don't already have it!
