Ответы и объяснения

last week I was invited to the concert of my favourite rap-singer. My friend and I bought the tickets and went to the concert hall where it took place.  About 1000 people came to this concert. At first he told about his biography and how he became a singer. Then we could enjoy his songs. Two girls helped him as back vocalists. The show was exciting! We supported the singer waving our hands.  I hope I will be able to visit his show again.
