Similar opening lines

[Poto]

Started to wonder how many songs have similar opening lines?

I can think of at least three

Dance of Death - Let me tell you a story
The Legacy - Tell you a thing
El Dorado - Got to tell you a story

Any more?

 

[Whooten]

In a time when dinosaurs walked the Earth...

 

[MarcoHietalaIM]

Let me tell you 'bout my life
Let me tell you 'bout my dreams
Let me tell you 'bout the things that happened
Always real to me

How about this Poto?
