G   320003
C   x30210
D7  xx0212
C/B x22010
Am7 x02010
Sometimes I find myself playing Am instead of Am7 and it still sounds good so if 
it is easier for you go for it

Strum Pattern:
DDUUD
From "My grandpa" to "sing some too" I strum once per chord.
On the split measures I just do DD for each chord. The split measures are G D7 on 
the last line of the verses and C C/B in the chorus.

Verse 1:
G                     C
My grandpa he's ninty-five
G                              D7
he keeps on dancing he's still alive
G                     C
My grandma she's ninty-two
G                                D7
she loves to dance and sing some too
G                          C
I don't know but I've been told
G                                        D7
if you keep on dancing you'll never grow old
G                       C              G          D7        G
