This is a very interesting approach to teaching or practicing the second conditional. My students loved it. Treat it like a listening class. my suggestions are: 1) teach them all of the conditionals (zero to third). 2) Have additional practice of all conditionals and then give this one without playing the song (for answers). 3) Play the song and check the answers. 4) Go through the common English phrases and unfamiliar vocabulary. Have fun!
