*You don't know me,but I know you well *You must be friends of mine *And as from today,I'm happy to say *You'll always be on my mind *It's been so good to see you all *I shan't forget a single day *Maybe you'll forget me *If I forget to remember some of your names *Now you know me,and i know you well *We'll be friends till the end of time *I promise one day,not too far away *We'll meet again and sing some song *Maybe you remember the time *The time we first met,we all sang along*
