This reminded me of a country song I've heard, so I looked for its lyrics on the web. Is Uncle's song like one of these?

SING ME AN OLD IRISH SONG
(Brendan Graham) As sung by Daniel O'Donnell, copied and pasted from www.google-lyrics.com

Sing me an old Irish song
Bring back the dreams that have gone
Sing me a love what's so strong
Bring me the days when we we're young...
And true, and I love you

And that old Irish song
Calling me back to my home
Where once again you sing along
To an old Irish song

I see the mountains, the valleys
The green fields below me
I walked the highways, the byways
The old people show me

I hear the songbirds
Remember the soft words
We spoke after dark in the glen
I hear you calling me
Your songs recalling me
Back to those days again

Sing me an old Irish song
Bring back the dreams that have gone
Sing me a love what's so strong
Bring me the days when we we're young...
And true, and I love you

And that old Irish song's
Calling me back to my home
Where once again we sing along
To an old Irish song

I remember the old days
How I loved the old ways of living
There was more sharing, caring
More loving, more giving
How times have changed
Life's been all disarranged
Since summers we laughed in the rain
But I hear you calling me
Your songs recalling me
Back to those days again

Sing me an old Irish song
Bring back the dreams that have gone
Sing me a love what's so strong
Bring me the days when we we're young...
And true, and I love you

And that old Irish song's
Calling me back to my home
Where once again you sing along
To an old Irish song

Sing me an old Irish song
Bring back the dreams that have gone
Sing me a love what's so strong
Bring me the days when we we're young...
And true, and I love you

And that old Irish song's
Calling me back to my home
Where once again you sing along
To an old Irish song

Sing me an old Irish song
An old Irish song

SING ME AN OLD FASHIONED SONG
(Larry Henley, Johnny Slate)

Sing me, sing me an old fashion song
Bring me, back in my mind to a time
Where my memories all come from
A good timing song, the kind
That makes you wanta sing along
A good old fashion hand clapping'
Knee slapping, foot tappin' song

Shoo fly don't bother me
Shoo fly don't bother me
Shoo fly don't bother me
I don't want your company
Flies in the buttermilk two by two
Flies in the buttermilk shoo fly shoo
Flies in the buttermilk skip to my Lou
Skip to the Lou my darling

Sing me, sing me an old fashion song
Bring me, back in my mind to a time
Where my memories all come from
A good timing song, the kind
That makes you wanta sing along
A good old fashion hand clapping'
Knee slapping, foot tappin' song

When I was young, I use to wait
Upon my master and bring his plate
And pass the bottle when his was dry
And wash away the blue tail fly
Jimmy crack corn and I don't care
Jimmy crack corn and I don't care
Jimmy crack corn and I don't care
The master's gone away

Sing me, sing me an old fashion song
Bring me, back in my mind to a time
Where my memories all come from
A good timing song, the kind
That makes you wanta sing along
A good old fashion hand clapping'
Knee slapping, foot tappin' song
(fade)
Sing me, sing me an old fashion song
Bring me, back in my mind to a time
Where my memories all come from
A good timing song, the kind
That makes you wanta sing along
