Bobby Vinton Beer Barrel Polka Roll Out The Barrel chords

Beer Barrel Polka Roll Out The Barrel by Bobby Vinton

Difficult one to tab this I found as all the recordings for this song seem to
slightly out of key (or it's my guitar!). However these chords seem to fit but any 
corrections welcome.Also not sure of the lyric last line sub-chorus 1?

Capo on 2 for correct key = A. Key change up one tone after first chorus.

Intro = G D G D G

Verse 1
G                     
There's a garden what a garden
                 D
Only happy faces bloom there 

And there's never any room there
                 G
For a worry or a gloom there 

Verse 2
G                            
Oh there's music and there's dancing
                     D
And a lot of sweet romancing 

When they play the polka 
                    G
They all get in the swing 

Sub-chorus 1
G     C
Every time they hear that oom pa pah                    
     G 
Everybody feels so tra la lah
             D
They want to throw their cares away
                              G
En luk dies shpere ah vas que va

Sub-chorus 2 
G        C
And they hear that rumble on the floor 
         G
It's the big surprise they've waited for 
             D
Then all the couples form a ring 
                                  G   G C
For miles around you'll hear them sing

Chorus 
C                                          G
Roll out the barrel we'll have a barrel of fun
G                                              C
Roll out the barrel we've got the blues on the run
C                                         F
Zing boom tararra ring out a song of good cheer
F                 G        C              F      G   C
Now's the time to roll the barrel for the gang's all here 

Repeat chorus + key change up one tone   
D                                A
La la la la la la la la la la la la oi oi oi
A                                D
La la la la la la la la la la la la oi oi oi
