Bookmark/Shortlist/Wishlist Plugin?

Sorry to bother you guys. I run a small live bands booking agency website.. I’m having real trouble trying to find a simple bookmarking (or favortes/shortlist) plugin, that will allow my browsing guest customers to view live bands page on my site, then shortlist, or favorite, any of the bands they like, so they can then send me the collated finished shortlist, so I can then phone the bands to ask if they are available for the customer’s event date. Is there a way I could use this for that?

Thanks a lot, Stu.
