Well the hot air sounds like Led Zeppeline. You can use it or hydrogen or helium to float balloons, and the white oak tree part sounds like The Kingston treeo, Get it oak and treeo. Huck huck, funny huh. Anyway they sang a song about down in some lonesome valley hanging from a white oak tree, so you probably want to look for something they might have done together.
Acourse it might be this:
Dark Night - Dave Alvin
hot air hangs like a dead man
from a white oak tree
people sitting on porches
thinking how things used to be
dark night
dark night
the neighborhood was changing
strangers moving in
a new boy fell for a local girl
when she made eyes at him
she was young and pretty
no stranger to other men
but doors were being locked at night
old lines were drawn again
CHORUS
I thought things like that
didn't matter anymore
I thought all the blood
had been shed long ago
dark night
dark night
he took her to the outskirts
and pledged his love to her
they thought it was their secret
but someone knew where they were
he held her so close
he asked about her dreams
there was a shot from a passing car
and the young girl screamed
REPEAT CHORUS
