Yes, it's an edited version of Lacrimosa, the eighth part of the Requiem. Only the first eight bars were written by Mozart himself, the rest was completed by F. X. Sussmayr after Mozart's death. Here's the lyrics: Lacrimosa dies illa Qua resurget ex favilla Judicandus homo reus. Dona eis requiem. Amen. (Tearful that day, on which will rise from ashes guilty man for judgment. Grant them rest. Amen.)
