Dweezil did this on tour recently and didn't mask the lyrics.
Oh, and lest anyone get upset, Ike Willis on vox.

I met Ike...he's a great guy.
Love that tune.

Snowflakes might get upset, but really YAWYS is pro alternate cultures. Embrace who you are. That’s the message. It’s what liberals SAY they’re for, while so often not.
Ike is VERY briefly in the documentary.
Watched it last weekend I don’t see that it presents enough framework or music to win over coverts.
And a lot of the “rare” footage is used in quick collages.
Frank’s wife Gail is interviewed but the kids don’t get a say.
I think the whole thing is a missed opportunity. If you know Frank’s story before going in it is still watchable but it isn’t the “ultimate” doc.
And while Tipper Gore is seen on camera (but silent) and Al Gore does speak, neither are identified in the PMRC footage while James Baker’s name comes up specifically several times.
