Got it today, took some time to learn the song and to get the talking going
Beginner Vocals (fan-spam method)
Medium drums (to keep the x4 up)
Expert Bass (not that hard on bass)
Hard guitar (rather hard on expert, swap down if you're not 100% sure you are really good/familar with it)
The most important is to activate star power at the same time, all 3 "human" players atleast (fan was just to keep streak / gain extra points) and you'll be fine. It's not at intiminating as it seems, just learn when to use star power and ALWAYS talk when you use it so all activate at the same time, this is when you'll get the points and good luck!
Edit: Might mention that:
Me, drummer, have experience with expert+, but you'll be fine if you know hard. The drums are sick at expert, but doable on hard / medium
My guitarist: Is good at expert, but Battery is a really hard song on guitar
My Basist: Tried hard, didn't net enough points on hard so he swaped to expert where we got about 30k+ just for he swaping
Good luck!
