this is a song we learned as children, does anyone know this one?

Oh, I have lost my underwear,
I don't care, I'll go bare,
bye, bye blackbird.
they were very close to me,
tickly, Yee hee hee, bye bye blackbird.
If you should ever come across them,
would you please tell them that I lost them,
Oh, I have lost my underwear,
I don't care I'll to bare,
bye bye blackbird.....
