[Intro]
Now I know that it can easily happen
To someone like me
I don't want to step on anybody's toes

[Verse 1]
Who knows how to find love
Think before you give your answer
Who knows what a mystery may bring

[Chorus 1]
Once in a life I'm a lucky man
If I can find the kind of love
That's going to last for me
Twice in a lifetime
Is one of those unspoken dreams
We usually reserve for fantasy

[Verse 2]
Who knows how we find love
Stop before you give your answer
Who knows where the mystery begins
I know, I know
I know because it's happening to me
I know, I know

[Chorus 2]
Twice in a lifetime
Is one of those unspoken dreams
We usually reserve for fantasy

[Verse 3]
Who knows how to find love
You stop before you give the answer
Who knows what a mystery begins
I know, I know
I know because it's happening to me
I know, I know

[Outro]
Oh I know, I know
I know because it's happening to me
I know, I know

Paul McCartney

Sir James Paul McCartney, born June 18, 1942, is the single most successful music artist of all time. He found worldwide fame as the bass player and vocalist for The Beatles, and has continued to enjoy commercial success long after the band’s breakup.

His post-Beatles projects—the most lucrative of which was the band Wings, alongside then-wife Linda Eastman—have been met with mixed critical reception but he still retains a substantial public following, regularly conducting worldwide arena tours well into his later years.

His album sales with The Beatles, Wings and solo endeavours combined come to over 100 million, and his net worth was estimated to be approximately $1.2 billion circa 2018. He was knighted in 1997 and is known for his activism.
