While I was eating dinner in a pub, the big screen was showing the preliminaries to a repeat of the USA v Wales football/soccer world cup game, with the sound turned down. The teams came out and lined up and the two national anthems were played and sung. Looking very carefully, I could just see the USA team members’ mouths moving, but they clearly weren’t putting much effort into it. The Welsh team members, on the other hand, were actually singing. I even mouth-read the word Gwlad (country). It wasn’t lip-reading, it was mouth-reading, like, their whole mouth. Sing (or don’t (see the Iranian team before their match)). Just don’t be wishy-washy about it.
