Sorry. Can't correct your English because I don't understand "Of course Jonny is a walking entertainment". Is that also a part of a song? Also, was your intention to ask someone to correct your English? Or was it to answer the question about the lyrics? You should know that understanding the meaning of the lyrics of a song requires much more than just understanding the language. There are websites that talk about song meanings, how to interpret the lyrics. If that was your intention, you would be better off Googling the song along with "meaning".
