From Youtube: a Coptic Orthodox liturgy celebrated in English by Fr. Mauritius Anba Bishoy at the El-Samaeyeen Cathedral, Sharm El-Sheikh, Egypt. The thick accents (as well as the microphones!) might be a distraction to some, but these give a fairly good impression of the divine liturgy of the Coptic Church.
Trivia: the beginning of part 1 (below) shows the priest choosing the Lamb that would be used in the Liturgy among the loaves of bread offered and inspecting the wine as the choir repeatedly sings Kyrie Eleison (it is actually sung 41 times: the reason usually given for this is because Christ was scourged with 39 lashes, and then crowned with thorns and pierced with a spear - yielding 41).
Here are the other videos: Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9, Part 10, and Part 11.
