I only recently picked up a copy of the vinyl via ebay.
According to janesaddiction.org Perry helped with the mix.

I think Perry does more than just help with the mix and I think these scans prove it.
If you look closely to that last scan it has the lyrics for Addiction.
Also in hind-sight I bet they wish they had a proof reader go over that 1st scan.
