真人版电影开头马戏团团长哼的歌便是动画版火车开动时的音乐：
Casey Junior's comin' down the track
Comin' down the track
With a smokey stack
Hear him puffin' comin' 'round the hill
Casey's here to thrill
Every Jack and Jill
Every time his funny little whistle sounds
Everybody hurries to the Circus grounds
Time for lemonade and crackerjacks
Casey Junior's back
Casey Junior's back
还有这首41版的歌也被哼过，不记得在是哪儿了，好像台词中也有这首歌的彩蛋
I saw a peanut stand, heard a rubber band,
I saw a needle that winked its eye.
But I think I will have seen everything
When I see an elephant fly.
I saw a front porch swing,
heard a diamond ring,
I saw a polka-dot railroad tie.
But I think I will have seen everything
when I see an elephant fly.
I seen a clothes horse, he r'ar up and buck
And they tell me that a man made a vegetable truck
I didn't see that, I only heard
But just to be sociable I'll take your word
I heard a fireside chat, I saw a baseball bat
And I just laughed till I thought I'd die
But I'd be done see'n about everything
when I see an elephant fly
鹳 （送子鸟）飞过弗罗里达的地图，暗示故事在这里发生，这个细节在真人版电影开头也有暗示美第奇兄弟马戏团是从弗罗里达南部出发
