Original Parody Lyrics

Somewhere over Cloudsdale, way up high
Past the clouds that you nap on way up in the sky
Oh somewhere over Cloudsdale, Rainbow Dash flies
And the rainbooms you dream of, rainbooms that you can do______

Someday I'll fly up really far
Fly to where the clouds are far behind me
Where Luna sleeps among the stars
Beyond where other ponies are that's where you'll find me

Oh somewhere over Cloudsdale, Rainbow Dash flies
And the rainbooms she dares to, oh why, oh why can't I?______

Well I see fillies of green and colts of blue
I can also see the Cake twins playing too
And I think to myself: what an equestrian world

Well I see skies of pink filled with all Pegasi
And Celestia's sunlit day, with Luna's moonlit night
And I think to myself: what an equestrian world

With Rainbow Dash's colors so pretty in the sky
Watched by Twilight, Rarity, and Pinkie Pie
Applejack's bucking apples, and Fluttershy's in her zoo
They had a magical connection, before...before they knew

I hear foals play in the winter snow
In the summer sun until the autumn blow
And I think to myself: what an equestrian world

Someday I'll fly up really far
Fly to where the clouds are far behind me
Where Luna sleeps among the stars
Beyond where other ponies are that's where you'll find me

Oh somewhere over Cloudsdale, Rainbow Dash flies
And the rainbooms she dares to, oh why, oh why can't I?
