Materials for the Lesson

I have two more days to prepare for the interview which is going to be held this Friday.
In the interview, I have to do a mock lesson for twenty minutes.
To show how the target grammar is used in real life, I looked for useful books for the lesson.
There was a book that introduced a lot of famous English songs. 
A song which was sung by Eric Clapton had lyrics I wanted to find.
I believe using such a material can motivate people to study English more.
I will have a fun thing to do this Saturday, so I will prepare for the interview until I get convinced.
