The "Hey Ba Ba Re Bob" above is probably a parody of the 1946 song "Hey! Ba-Ba-Re-Bop!". Here are the lyrics to the clean song:

HEY! BA-BA-RE-BOP!

HEY!-- BA-BA-RE-BOP,
HEY!-- BA-BA-RE-BOP,
HEY! --BA-BA-RE-BOP,
HEY!-- BA-BA-RE-BOP,
HEY!--BA-BA-RE-BOP,
Yes,--your ba-by knows,

Ma-til-da Brown-told Old King Tut,-
If you an't say RE-BOP, keep your big mouth shut,

--sing-'in HEY!--BA-BA-RE-BOP,
HEY!--BA-BA-RE-BOP,
HEY!--BA-BA-RE-BOP,
Yes,----your ba-by knows,

Ma-ma's on the chair,
Pa-pa's on the cot,
Ba-by's in the crib blow-in'
his nat-'ral top.

- HEY!--BA-BA-RE-BOP,
HEY--BA-BA-RE-BOP,
HEY!--BA-BA-RE-BOP,
Yes, ---your ba-by- knows----

Up on the moum-tai,
look-in' at the sea,
Look-in'for that cat that
stole my ba-by from me,
sing-in'

HEY!--BA-BA-RE-BOP,
HEY!-- BA-BA-RE-BOP,
HEY!--BA-BA-RE-BOP,
Yes,--your ba-by knows.
