Style
The BeatleBrony's style is that of a cover band. They take fameous and obsucure songs by well known British rock band The Beatles and re-write the lyrics to fit into the overall My Little Pony: Friendship is Magic universe. One several early recordings of theirs they used instrumentals of the original songs and then recorded their voices over that. Eventually they switched to an almost inteirly live approace with the actual members playing the instruments.
