From the recording The Orange Blossom Special

I had played this on the harmonica for years in Bardstown, KY entertaining tourists at the Old Stable restaurant. I just had to include it on this recording when I found myself in the studio with one of the best fiddle players, Mike Cleveland.
The real passenger train, The Orange Blossom Special, introduced in 1925 and put on display in Jacksonville, Florida is what inspired the Rouse brothers to write this song.

Lyrics

Look yonder coming, coming down the railroad track. Look yonder coming, coming down the railroad track. It's the Orange Blossom Special, bringing my baby back.
