Here's my transcription from the Jim Kweskin recording, which is more-or-less the chorus, sung twice and jazzed up the second time:

SOMEBODY STOLE MY GAL
(original by Leo Wood 1918)
[as recorded by Jim Kweskin]

Somebody stole my gal.
Somebody stole my pal.
Somebody came and took her away.
She didn't even say she was leavin'.

Now, her kisses I miss so,
She's missin' mine, I know.
Yeah, gee!
If she could see,
Ah, me, her lonesome pal
You' know that she'd come runnin' right back to me,
Now, somebody stole my little gal.

[instrumental break]

Yeah, how, Somebody stole my gal.
Somebody stole my little pal.
Somebody came a-runnin' and he took her away.
She didn't even say that she was leavin'.

Now, her kisses, well, I miss so,
She's missin' mine, I know.
Yeah, gee!
If she could see,
Ah, me, her very lonesome pal
You' know that she'd come runnin' right back to me,
Somebody stole my gal.
