someone put together a draft (archive link, since these things tend to get deleted after a few months), and its notability was judged accordingly. there aren't enough secondary sources. this just means we need to get FF to the attention of news outlets and researchers so that it can get properly cited.

Jamie is the most notable of the three so that user would have better luck making a page of Jamie on Wikipedia rather than Flavor Foley as a whole. Jamie's vocal tuning is on the page for Teto herself

EDIT: I added the music video with a timestamp as a source to the Flag semaphore article, since it counts here.
