"What is a Youth"

Lyrics by Eugene Walter

Music by Nino Rota

Vocal by Glen Weston

What is a youth? Impetuous fire.

What is a maid? Ice and desire.

The world wags on.

A rose will bloom

It then will fade

So does a youth.

So do-o-o-oes the fairest maid.

Comes a time when one sweet smile

Has its season for a while...Then love's in love with me.

Some they think only to marry, Others will tease and tarry,

Mine is the very best parry. Cupid he rules us all.

Caper the cape, but sing me the song,

Death will come soon to hush us along.

Sweeter than honey and bitter as gall.

Love is a task and it never will pall.

Sweeter than honey...and bitter as gall

Cupid he rules us all

What is a youth? Impetuous fire.

What is a maid? Ice and desire.

The world wags on.

A rose will bloom

It then will fade

So does a youth.

So does the fairest maid.

Comes a time when one sweet smile

Has its season for a while

Then love’s in love with me.

Some they think only to marry,

Others will tease and tarry,

Mine is the very best parry.

Cupid he rules us all.

Caper the caper, but sing me the song,

Death will come soon to hush us along.

Sweeter than honey and bitter as gall.

Love is a task and it never will pall.

Sweeter than honey…and bitter as gall

Cupid he rules us all
