Answer:
A darkΒ-colored creature serenaded by Lennon and McCartney.
I'm known as the king of the jungle and have a magnificent mane. What am I?
I am a animal i have sharp teeth i am the of the forest
Though desert men once called me God, today men call me mad. For I wag my tail when I am angry. And growl when I am glad.
To you, rude would I never be, Though I flag my tongue for all to see.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
