Shadowfax

Please tell me if this is too shabby. I did it off the top of my head in math class, but I really liked it.

Pegasus was less wild than he of the mearas
Tamed by a bridle of gold
The only one to lay claim the Lord of Horses;
The Grey and now the White Wizard, Gandalf

Black became he who trod at night and
White became he in the morning’s light
The only one to lay claim the Lord of Horses;
The Grey and now the White Wizard, Gandalf

Beyond any trappings he carried but one rider
And for this his testament, he was the finer
The only one to lay claim the Lord of Horses;
The Grey and now the White Wizard, Gandalf
