His German website has information about his new German CD release.
For the Germans he did a cover of "Hard Rock Hallelujah!"
No, I'm not kidding.
The Germans have him pegged as a heavy metal squirrel, so heavy metal he does. I'm not sure how his cover of "La Bamba" fits in there.
Then again, on his second Finn release, Kesä Seedee, he does a cover of Lordi's "Would you love a Monsterman?"
