Logitech guitar for Wii compatibility question

[mooncancook]

I got a Logitech GH guitar for Wii from a friend today, now I just need to buy some games for it. Can anybody tell me what RockBand games it is compatible with? I'm interested in the RB Beetles and GreenDay, but don't know if they will work with the guitar. I tried searching about it but I couldn't find a definite answer.
