Regretful Decline and Alternative Plan

Dear Hung, I hope this email finds you well. I wanted to let you know how sorry I am that I won't be able to attend the My Tam liveshow tomorrow. Unfortunately, I have a prior commitment that I cannot cancel. However, I would love to make it up to you by suggesting an alternative event that we can go to together. There is a local music festival happening next weekend, and I think it would be a great opportunity for us to enjoy some live music and have a good time. Once again, I apologize for not being able to join you at the My Tam liveshow, but I hope you understand. Let me know if the music festival sounds like a good plan to you. Best regards, [Your Name]
