听力原文：Good evening, ladies and gentlemen and welcome to tonight's concert by Funky Funk

y. We' II start the show shortly but first, the members of the band would like you to know that there will be on sale of their latest CD "After the rain" after the performance. They' II be happy to sign your copy. The CD is usually sold in stores for $18 but tonight the price is $9. When you buy a CD, you'll also receive a free cap with the band's logo. We hope you' II take part in the sale because all the proceeds received will be donated to local organizations involved in community activities for poor children. These groups really make a difference in the lives of children through education in your neighborhood. Thank you and enjoy the show.
