Please give a link to Passover songs

[Masha]

Hi,

We are having a Passover celebration with a large group of unmusical friends. I have very rudimentary piano-playing skills. My son plays the guitar. I tried to find on the Internet the (simple) piano and/or guitar scores and lyrics of popular Passover songs, but no luck. Does someone have a good link? I'd like to do have accompaniment on a musical instrument - I think it's merrier. Thanks in advance. (I especially like Echad Mi Yodea).

Thanks Muman! 

Does your link also have the music score? I can only see the lyrics.
