Dear Allen, How are you doing? Knowing that you take a great interest in music, I am writing to invite you to join us in the Music Festival to be held in our school. The festival is scheduled to start in the school hall at 8 a.m. on June 10, lasting about 3 hours, when a wide variety of performances will be put on. It is said that a large number of students as well as some professional singers are going to participate. Additionally, you are welcome to show up with your guitar on the stage, which will add color and fun to our festival. I would be more than delighted if you could come and share this joyful moment with me. Looking forward to your early reply.,
