Preparing FCE exam,Please,Could anyone correct this?-thanks!

I must answer the question in 120-150 words in an appropiate style.

The question is: I have just received an email from my English friend Alex asking if I´d like to go to a concert by my favourite bad,Red Stone.

And this is my answer:

Dear Alex

Thanks a lot for your email.  I have been waiting for you for two weeks.  Are you really telling me which Red Stone are going to come to the city on 21 of July?, If it´s true I really want to go! it´s That's awesome!.
Don´t worry if you don´t know so much about them, they are one of the a kind.They have recorded six albums arround the world.Theirs songs have been number one in England for one year.

I would prefer to be stand because when the concert starts we are will be jumping and shoutting crazily.

I´m pleased for your hospitality  Thank you for inviting me, and I think that the The day after the concert we could have to go to the theater to watch the last latest Steven Spielberg movie.

Can´t wait to see you! 

All the best, 

Mario
