Disney had a show within it's regular Sunday show called "Willie and the Yank, but also known as Mosby's Maurauder's.

That show was different from The Grey Ghost

Willie and the Yank did had lyrics:

Both Reb and Yankee Strangers,
They Called us Mosby's Rangers
North and South they know our fame
Grey Ghost is what they called me
John Mosby is my name.


The Grey Ghost had a voice-over:

"We took our men from Texas, Kentucky, and Virginia; from the mountains and the backwoods and the plains. We put them under orders — guerrilla fighting orders, and what we lacked in numbers, we made up in speed and brains. Both Rebs and Yankee strangers, they called us 'Mosby's Rangers.' Both North and South they knew our fame. Gray Ghost is what they called me; John Mosby is my name."
