>>42281506 (OP)I did similar. On school talent show I sang a de-ponified Lullaby for a Princess, with pony words replaced by normal words. I had my friend playing the piano along, I gave him the note sheet, never told him where is it really from, just told it's an old song. No one suspected it was an MLP song, the audience recognized it just as a cool song

> Once did a pony who shone like the sun> Look out on her kingdom and sigh> She smiled and said, "Surely, there is no pony> So lovely and so well beloved as I"Edited:
