    Am              G                            Am
Last night as I lay dreaming,of pleasant days gone by,
                               C                G
Me mind being bent on rambling,to Ireland I did fly,
 Am                       C                  G
I stepped on board a vision,and followed with a will,
      Am              G                              Am
Till the first I came to anchor at the cross at Spancil Hill,
