The tune is “Sh-Boom” and the words are in German; they’re just not the right words! Perennial parodists, J.B.O. savaged the lyrics. No worries. You can follow along with the translation below.

Life is like a dream
Life is like a dream
Dü dü-dü-Düp – chi-bum
…
Life is like a dream – chi-bum
If I can eat pizza on holiday with you – chi-bum
And with you, hand in hand, on the seashore stand – chi-bum
And then in the moonlight see your beautiful eyes – chi-bum
Life is like a dream
With you, I’m going to the altar
Chi-bum – Say loud and clear, “Yes”
…
Hear bells ringing – chi-bum – a sound, a-ling-a-ling
And angels singing – chi-bum – badu-a-you-a-dip, yes

Life is like a dream – chi-bum
If you’d get drunk with me at my favorite pub – chi-bum
And afterwards get so aroused during sex are that you sing opera arias – chi-bum
Life is like a dream with you
Dü Düp-Düp-Düp-chi-bum
…
Every day and every night I’d like to be with you
And I want to tell you everything
But these lines are too damn short to make myself clear
…
Life is like a dream – chi-bum
If I ever come back and we make up after our last fight- chi-bum
And even nicer if I could finally get to you kick
All your bad habits – chi-bum
…
Life is like a dream
I’ll go to the hairdresser with you
Chi-bum – mess up the perm
…
Hear bells ringing – chi-bum – a sound, a-ling-a-ling
And angels singing – chi-bum – Hallelujah, Hallelujah
Life is like a dream
Life is like a dream with you
…
Dü Düp-Düp-Düp-chi-bum
Dü Düp-Düp-Düp-chi-bum
Dü Düp-Düp-Düp-chi-bum
Dü Düp-Düp-Düp-chi-bum
…
Yes, life is like a dream – chi-bum
We talk for hours and you
Pretend the whole time I’m not high off my ass?!
And I’ll simply try to defend myself and say “I’m a lazy stoner!” – Chi-bum
And you’ll simply say “Shut up!” … – Chi-bum
Life is like a dream
Because of you, I’m going to become a lawyer
So I can get divorced soon
…
Hear bells ringing – chi-bum – a sound, a-ling-a-ling
And angels singing – chi-bum
Blue today, tomorrow, and the day after that!
…
Life is like a dream
Life is like a dream with you
Dü Düp-Düp-Düp-chi-bum

Remember Richard Reid? Ronnie does.

At the outset, I feel the need to get this out of my system:

What’s the difference between a ukulele and an onion?

No one cries when you cut up a ukulele.

What’s the difference between a ukulele and a trampoline?

You take your shoes off to jump on a trampoline.

Why do so many people take an instant dislike to the ukulele?

It saves time.

All joking aside, the amalgam of sweetness and insouciance in this rendition by Reneé Dominque was enchanting.
