Need help tracing song

[StrangeBehavior]

Hi all, My first post

This one is from the Sixties, here are the lyrics - does anybody have any suggestions?

when spring begins to sprout
bees start to buzz about
and songbirds sing
of birds and bees and things
I'm told reliably
that every bird every bee
when someone special they see
feels exactly like me
it comes naturally

lets together both learn how
boy and girl
make a world
make the facts about life now
beautifully
clear to me

when we go walking out
and start to talk about
the little things
like birds and bees and things
I'd like to sample with you
what all the birds and bees do
see for myself if it's true
that it's worth the hullabaloo
that we all ???

lets together both learn how
boy and girl
make a world
make the facts about life now
beautifully
clear to me

make the facts about life now
beautifully
clear to me

the same as the birds and the bees
