Playing Raffi brings me joy, even when there aren't kids around. I got these chords from watching a video on youtube of him performing (http://www.youtube.com/watch?v=8U3UDl0bUHA) Each verse goes like this:

^DmYou gotta sing when the sp^Airit says s^Dming ^DmYou gotta sing when the spirit says s^Aing ^DmWhen the spirit says sing, you gotta s^Gm7ing right along ^DmSing when the sp^Airit says s^Dming

Then repeat for each verse: You gotta clap... You gotta hum... You gotta snap... You gotta swim... You gotta stomp... You gotta hush... You gotta sing... The ending goes like this:

^DmYou gotta sing when the sp^Airit says s^Dming ^Gm7You gotta sing when the sp^Airit says s^Dming ^Gm7You gotta sing when the sp^Airit says s^Dming ^DmAnd you gotta stop when the sp^Airit says s^Dmtop

For the two outro chords, play the top 3 strings (GBE) at the 7th and then 8th frets. Note: the Gm7 is played as 353333 Enjoy!
