The Mass of St David, King and Prophet

Earlier today a friend sent me a message saying he was watching online, virtually attending in fact, the Mass for the Feast of St David the King and Prophet from the SSPX St Thomas Aquinas seminary in the US. I now see that the New Liturgical Movement have a post about the Feast, its history and propers which can be seen at The Mass of St David, King and Prophet

I imagine that falling on the same day as the Martyrdom of St Thomas of Canterbury it has historically attracted less attention in this country than it might otherwise have done, although Old Testament figures receive considerably less public veneration in the West than in the East.
