I haven't met Amy Lee yet, but I've been trying to get her to play at my wedding next year. I contacted Andrew Lurie using the contact info on her site, and he hasn't replied yet. So I tried some celebrity booking agency, but they haven't gotten back to me either. I even tried posting on EvThreads in the Ask Amy section, but no reply there either (of course... she's probably really busy). So I PMed Tim, but he hasn't logged in for awhile... so if it's still to no avail in a few months, I do have a backup. Have you heard of YFL (Your Forgotten Love)? They're awesome. They sound a lot like Amy Lee.
