Mainly Norfolk seems to have three main types of links we might want to link to:

https://mainlynorfolk.info/watersons/index.html (artist)
https://mainlynorfolk.info/watersons/records/forpenceandspicyale.html (album)
https://mainlynorfolk.info/watersons/songs/countrylife.html (work)

We currently don't validate these at all.

They also redirect to HTTPS so we might want to do the same.

Even though they allow using www subdomain, it’s prominent neither in search engines nor their “About” (Welcome to mainlynorfolk.info.) so we might want to do the same.
