There wasn’t really an ‘easy way’ to tab the key change in this song…
You can either play without the capo, using barre chords for the 1st part of
the song, or use the capo and play barre chords through the 2nd part.
I decided to go with the capo….
The other way you could play this is to quickly move the capo up a fret (to 2nd)
when the key change happens, and just play the same chords all the way through.

Play this with a capo on 1st fret.
All chord names and shapes are relative to position of capo.

INTRO

It was back in ’36 when country music came to town,
Tex had wrote a few songs and he’d come to put his music down.
Regal Zonophone cut those early 78’s,
And the man said on the wireless, “Country’s really big these days”.

We heard him sing about where the white face cattle roam,
And Australia came to see the Buddy William’s Travellin’ Show.
And then Slim hit the road and soon became a household name,
They were saying back then, “Country’s really big these days”.

Yeah, break out the fiddle, resin up the bow,
Like they did back then on those old time country shows.
‘Cause we remember our roots and the pioneers who paved the way,
Now everybody’s saying, “Country’s really big these days”.

G C (key change) Ab
INSTRUMENTAL

There’s been a lot of changes in the music industry,
We’re on compact disc now and country’s on MTV.
Old Tex and Buddy wish they were around today,
‘Cause everybody’s saying, “Country’s really big these days”.

Yeah, break out the fiddle, resin up the bow,
Like they did back then on those old time country shows.
‘Cause we remember our roots and the pioneers who paved the way,
That’s why everybody’s saying, “Country’s really big these days”.
Yeah from Perth to Goondiwindi, country’s really big these days.
Yeah, from Cairns down to Burnie, country’s really big these days.
