Help with a leaving song.

Hi i need some help. I am in high school doing my GCSE's and have just found out that my favourite teacher is leaving. He teaches me for music and i have had him for 4 years now and he has taught me and my classmates so much. We are having a party and have a picture slide show to show him and we want to play the perfect song, as he will appreiciate it. I wonder if anyone has any good ideas for a song??? Help would be great.

Thanks

I think I may have one..

Try "Horizon "by The Cinematic Orchestra ft. Niarra Scarlett .

One of my alltime favourites!!

If you can't find it , just sent me a pm okay?

Also , a bit more mainstream (but might be appropriate for the occasion ):
Thank you for the music - Abba
Music - John Miles

What about Ryan Cabrera "I Will Remember You"
