A little girl’s moving story of some dinosaurs who fell in love and then became extinct has left the internet in absolute bits.

The emotional and incredibly poignant song, sung by three-year-old Fenn and performed with the help of her dad, London-based musician Tom Rosenthal, takes us through the last moment of a dinosaur’s life before the Big Bang.

It is a song about love. It is a song about eating a balanced diet. And it is a song about the cruel, rapid nature of death.

If the last line, “But they didn’t get to say goodbye” doesn’t leave you on the verge of tears, then honestly we don’t know where your heart is.

The moving ballad has achieved huge levels of fame on social media, probably due to the fact it has the power to emotionally destroy us all.

There is so much truth behind such simple words. 

Spotify is already clamouring to get the track uploaded on its platform. But Fenn isn’t fussed about her newfound fame.

Rosenthal told CNN his daughter can “just about count to 20” so she doesn’t really understand that half a million people have listened to the song.

“I told her that her grandma liked it and she wasn’t that fussed about that,” he said. “She enjoyed doing it, she listened to it when it was done and then she was gone.”

Like many of us, Rosenthal was also impressed by his daughter’s grasp of science. He and Fenn are regulars at the Natural History Museum in London, but he hadn’t realised she was taking it in, he told Buzzfeed News.

The lyrics of the song go a bit like this:

Dinosaurs eating people,

Dinosaurs in love,

Dinosaurs having a party,

They eat fruit and cucumber.

They fell in love,

They say ‘thank you’.

A bing bang came,

And they died.

Dinosaurs, dinosaurs fell in love,

But they didn’t get to say goodbye.

But they didn’t say,

Goodbye.

HuffPost UK has contacted Tom about the song and will update the piece when we hear back.
