A huge percentage of Carlos Peron's library of work has been re-released and remastered on Peron Digital. I found all the great Yello related Peron tracks in superb digital sound .

Kong Fu Pogo - with Dieter vocals!
Happy New Year - with Dieter vocals!
Shooting The Dark - Boris and Carlos calaboration!

Plus new Carlos releases :
You gotta say yes to antother excess (Schränz mix) - My favorite. Lots of original lyrics and samples! Great track!
You gotta say yes to antother excess (Old school mix) - same version that appears on Talks To The Nations album.
You gotta say yes to antother excess (Sir Henry Mix) - techno version!
You gotta say yes to antother excess (Guitar hero mix) - Rock guitar version!
Carried to excess - uses the line "You will find excess in the jungle!" - another favorite track!
Barfly - Lots of Yello lyrics and samples!

I found everything on US iTunes except Happy New Year. But emusic has it.
