My friends and I got entered into a Beatles Rockband competition for a children's home fundraiser against other teams of community volunteers on March 26th. We're using "I Wanna Hold Your Hand" in easy mode and don't want to make fools of ourselves. We're all non-regular rockband players, so we're just looking for the best way to score the most points as a team. Should we use overdrive at certain times only, or every time we can? Any tips you can give would be most helpful!
