YMCA "Learn how to swim" commercial jingle

Back in the early '70’s there was a YMCA commercial enticing you to take swimming lessons from them. It had lines like (and I’m probably not remembering them correctly):

“There is safety in numbers, but there’s danger, too
So you have to swim well so nothing will happen to you
Learn how to swim at the YMCA”
(repeat last line to fade)

I don’t know why this pops into my head from time to time.

Anyone else remember this?

I remember bits and pieces of it.

“If you like the water,
then you really oughta
learn how to swim at the YMCA.”

and,

“Don’t go swimming alone.
Don’t stray away from the shore,
or else you might not never
go swimming no more.”
