Found the following, too.

"I had my dad write the lyrics down for me, but I can't help you with the artist, score, or even the name of the song. My dad used to sing it to me and my sister when we were little, too.

Tommy went a-walk boo boo walk boo boo walkin'
Down to the field boo boo wield boo boo 'ield
To mow his weeds boo boo 'eeds
When a snake bit his hell boo boo 'eel
Toomaray toomaray tomeray

Tommy said Dad boo boo ad boo boo ad
Please get my gal Sal boo boo 'al boo boo 'al
'Cause I think I will die boo boo 'ie
And I know I shall boo boo 'ow
Toomaray toomaray tomeray

Sally said Tom boo boo 'om boo boo 'om
Why did you go boo boo 'o boo boo 'o
Down field boo boo 'ield
To watch your weeds grow boo boo 'ow
Toomaray toomaray tomeray

Tommy said Sal boo boo 'al boo boo 'al
Why don't you know boo boo 'ow boo boo 'ow
When the grass gets ripe (or "high") boo boo 'ipe
It's gotta be mowed boo boo 'owed
Toomaray toomaray tomeray

Tommy did die boo boo 'ie boo boo 'ie
And to heaven did go boo boo 'o boo boo 'o
Didn't mow his weeds boo boo 'eeds
'Cause they laid him low boo boo 'ow
Toomaray toomaray tomeray "
