I know there's already a tune request on here but I've been trying to work out the chords to sing along to and something doesnt sound right.
I'm listening to the recording off of Blow Boys Blow by Maccoll and Lloyd, here is what I have so far:

G                                 Em
While cruising round Yarmouth one day for a spree
G                                  Am
I met a fair damsel the wind blowin free
G                                       Em
I'm a fast going clipper my kind sir said she
G                         Am          Em
I'm ready for cargo my hold is quite free


G                         Em
Singin Falderal laddie I'd falderal day
G                      D    G
Falderal laddie I'd Falderal day


Something doesnt sound quite right, maybe wrong key or something?

Thanks in advance!
Mathew
