The original song shows the line in context:

You’re the cream in my coffee,
You’re the salt in my stew
You will always be my necessity,
I’d be lost without you.
You’re the starch in my collar,
You’re the lace in my shoe
You will always be my necessity,
I’d be lost without you.
Most men tell love tales,
And each phrase dovetails
You’ve heard each known way,
This way is my own way:
You’re the sail in my loveboat,
You’re the captain and crew,
You will always be my necessity
I’d be lost without you.
(Repeats of verses 1 and 2)
You give life savor,
Bring out its flavor,
So this is clear, dear,
You’re my worcestershire, dear!
You’re the sail in my loveboat,
You’re the captain and crew,
You will always be my necessity,
I’d be lost without you.
You will always be my necessity
I’d be lost without you.
