Here’s an hour-long video that describes some hows and whys of liturgical worship, via the Internet Monk.
Here’s an hour-and-a-half long video, “Instructed Eucharist,” in which an Anglican priest teaches on the church history and biblical themes underlying Communion (which Anglicans often call the Eucharist) and then briefly explains each part of a Sunday morning liturgical worship service. (If something about the other guy grates on you a little, try this video instead.) The same information in written format is here.
If you have interest in these things, the videos are worth spending time with.
