This has been posted on a couple of Facebook pages just; I know nothing more about it than this -will try to get more info/verify it:
Secret Show #4 – Today on Troubadour – Santa Monica CA
Edit: we’ve found the original source:
It says RHCP are rumoured to be playing the secret show at The Troubadour tonight with Bob Forrest’s Thelonious Monster in support.
We are still trying to verify this so watch this space! Will update if we find out anything else.
Thanks to Rain Dance Maggie, Ana & Shalhevet for the updates
