D (xx0232@1)               GOh (320003@1)little town of Bethleham
    D (xx0232@1)      A (x02220@1)      DHow (xx0232@1)still we see thee lie
B (x2444x@1)                EmAbove (022000@1)the dark and dreamless sky
    D (xx0232@1)    G (320003@1)      DThe (xx0232@1)silent stars go by
B (x2444x@1)                 F#For (244322@1)in the dark sky shineth 
    G (320003@1)         F#The (244322@1)everlasting light
D (xx0232@1)                    G (320003@1)                  
The hopes and fears of all the years
D (xx0232@1)        A (x02220@1)  DAre (xx0232@1)met in thee tonight


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