This archived radio program includes a recording of I'M OLD BUT I'M AWFULLY TOUGH, recorded by Cal Stewart in 1909. (Click to play.) The song begins 00:34:46 from the beginning of the program. Here's my transcription (with a few gaps).

I'M OLD BUT I'M AWFULLY TOUGH

I'm a jolly old fellow from way back in New England
Where apples and peaches and ... do grow
Where the girls they are handsome, the boys they are likewise.
The same I would have you to know.
I came to your city, your sights for to see,
The ... and the great Union Square.
I came for to ride in your 'lectric streetcars
And wink at your pretty girls there.

CHORUS: But I'm old but I'm awfully tough, ha-ha-ha-ha!
Old but I'm awfully tough.
And the belles they do say, "Uncle Joshuway,
You're old but you're awfully tough."
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
I'm old but I'm awfully tough.
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
Ha-ha-ha, ha-ha-ha, ha-ha-ha, ha-ha!
I'm old but I'm awfully tough.

I'm a jolly old fellow from way back in New England,
A jolly old fellow, you see.
I'll play ... but I'll give you the joker
And beat an odd diamond or three.
A jolly old fellow, my age never mellow,
Although I am near seventy-three.
Away with your brokers but give me the joker,
For a jolly old fellow you see. CHORUS
