I don't have the liner notes, but doesn't Mark Vreeken play something on one of the last two albums. I could be totally wrong.

I don't think he played any instruments, but when the Hip returned from recording with Hugh Padgham in the Bahamas, they felt they needed a couple more songs, so Mark Vreeken ended up recording "Are You Ready" and "Silver Jet" at the Bathouse.
