The music for our song

Once upon a time
I caught a little rhyme. 

I set it in the brightest light
but it flew out of my sight. 

I chased it all over the bar
but it wasn´t very smart. 

I caught it in a song
but it seemed to be all wrong.

 I followed it round the world,

but it turned into a playful curl.

When I fed it with a spoon
it became a blue lagoon.

Then it grew into a kite
and flew far out of sight.

I don’t know where it went,

Maybe hidden in a purple tent,

Always full of sweet content,

Maybe that’s what I meant.
