Dear Mr Wade,
I would like to apply for the job at your Latin American Club as a DJ, which I saw advertised in "The Weekly News".
I am a seventeen-year-old student. At the moment I am studying in Comprehensive School.
I would enjoy workin as DJ because I am energetic, spontaneous and humorous. I think I am suitable for the post.
I would be happy to attend an interview at any time convenient to you.
Yours sincerely,
XYZ
