I've done these on guitar and bass but can't find a good song to do with vocals.

So far I've done:

Guitar: - Here It Goes Again
Bass: - Learn To Fly

And I've heard that '29 Fingers' is best for drums as it only has Red and Blue notes in it but I'm so good at snare rolling yet.

What's the easiest song to complete 100% on vocals, expert?

And what have you completed these achievements on?

I would say give Sabotage on expert as there isn't any pitch level to it. I get 99% on it everytime i do it and i can only do vocals on Medium/Hard, so i am sure you can do it.

Vocals - Thrasher
Drums - Gimme Shelter, I Think I'm Paranoid

They'll play hard or they're not going to be here.

I find "Blinded by Fear" much easier to FC on Vocals, especially in Band Quickplay. FCed it on sightread in band quickplay.

Anyway, for vocals I did "Blitzkrieg Bop". Extremely easy. For drums, you can't go wrong with 29 Fingers in band quickplay. Do not use overdrive at all and make sure your bandmates hit the first overdrive unison and you won't have to do any snare drum-rolls.

is it true that u can only strum up on bass to get the 100% achievement?

Yes.

in my case i had to strum down. Lefty FTW!

I found that while playing Sabotage on expert for the vocals, you can rub the mic on carpet and you will get 100%

Epic is pretty easy. I can't do expert singing, but I can get 98% on it.

Sabotage doesn't work because the "talking" parts are too wishy-washy.

I suggest Blitzkrieg Bop or Paranoid. I think I've FC'ed them both on vocals.

Easiest song on drums is Gimme Shelter. There's also some other song by the Pixies... I don't remember what it's called, but it's DLC, so don't do it unless you already have it.

For drums i would play I Think I'm Paranoid, Really easy and for vocals i have always tried sabotage and never got it so i dont really know.
