The best way to play this is with a capo on the 1st fret. It sounds great with a 12 string!
I will list mandolin/original chords at the bottom.
Intro (Capo 1): D Am7 G Am7 D Am7 G repeat
Those same chords play the same way throughout the verses and chorus'
D Am7
Lazy old day
G Am7 D
Rolling away
D Am7 G
Dreaming the day away
Don't want to go
Now that I'm in the flow
Crazy amazing day
[ Tab from: https://www.guitartabs.cc/tabs/e/enya/lazy_days_crd.html ]
One red balloon
Floats to the moon
Just let it fly away
I only know
That I'm longing to go
Back to my lazy day
G Bm A D
And how it sings and how it sighs
G Bm A
And how it never stays
Bm A D
And how it rings and how it cries
G Bm A
And how it sails away...
away... away....
