D                 G
Oh little town of Bethleham
    D        A        D
How still we see thee lie
B                  Em
Above the dark and dreamless sky
    D      G        D
The silent stars go by
B                   F#
For in the dark sky shineth 
    G           F#
The everlasting light
D                      G                    
The hopes and fears of all the years
D          A    D
Are met in thee tonight


There are more verses, but that would take a long time, so be happy with that.
