I don’t know John Denver. However, I’ve heard him.        
He preferred country music for pop music. I like his        
songs and sometimes I keep listen all day. He              
made lots of records and his music had broadcast on      
the radio. He was not just the singer but a song writer.          
When people were angry with society but didn’t think    
well of political leaders, he begins to turn to this              
subject with other singers. They made o fun of them          
by singing songs full of angry. Though Denver died,          
country music have become more and more popular.     		1. _____
