An ongoing thread by Twitter user @TimeCommando with over 1,000 retweets and 4,000 likes at the time of writing shows a number of searches on the Megan's Law website, a site that allows you to search for members of the sex offender registry, coinciding with chorus members' names, insinuating that these are the same people. This has not been confirmed though, and many have pointed out that these could be different people.
Hahahahahahahahaha.
For at least one of them, the picture matches.
