Hey, long time lurker, first time poster here!
I'm in a ska/punk band and we were thinking about doing a Weezer cover. Say It Ain't So was a first choice for us, but we were open to ideas.
Below is the chorus to Say It Ain't So on a saxophone. I'll probably eventually put some more Weezer saxophone covers on there. Again, we'd be open with ideas on what to cover. I'm thinking El Scorcho with the sax for the solo!http://www.youtube.com/watch?v=iW1pVfRLKf8
You might be able to do something fun with Surf Wax America.
I think you sound pretty good so far! Do you have any Weezer sheet music, or are you just playing by ear? I have sheet music for Blue, Pink and Green - I refer to them all the time. Keep up the good work!
