Karaoke

On April 11, my two friends and I went karaoke after classes.
I had cold and had a sore throat but I went because I didn't go for a long time.
When we arrived at downtown, we wanted shopping, too.
We gave it up so that we had only a little money.
We sang many songs for two hours.
I 'd like to sing well. Will someone please tell me about it?
