Just another quick tab as there wasn't one for Fireflies. I tried my best 
listening to it, just leave it capo-less and in standard tuning, if you can do a 
better one please do

G                            
I'm living on the river once again
D                           C
Come calling on me when you can
G
Been keeping to myself these days,
D           C 
I thought you knew
D                    C
Been following my own trail

D
Got lost in the river
            G      C
Sound and the starry skies
D              G        C
It's a time of year for fireflies

G
Been travelling away from the eyes of men
D                    C
I left the city once again
G                                   D       C
Been following the clues left by my brother Dan
D                          C
Who's gone ahead out on the trail

D
Got lost in the river
             G      C
Sound in the starry skies
D              G        C
It's a time of year for fireflies
