This is a song that my students love to sing on Fridays. It's to the tune of McNamara's Band and has a really peppy tempo. The first thing my students say to me when they walk into class on Friday is "On va chanter la chanson de vendredi?" Your students will love it!
If you don't know the tune, you can go to Grooveshark and search for MacNamara's (use this spelling) band instrumental to hear a great version of the song.
