The following quote from http://support.apple.com/kb/HT5760 may help (but I'm not sure you can do 60 in one message). The link shows how to disable group messaging and that does still allow multiple recipients.
If you send a message to multiple recipients without group messaging in use by the sender and all recipients, an individual message will go to each recipient using either SMS or MMS. Responses to these messages will be delivered only to the original sender in separate messaging threads.
