I was blessed to be able to attend said Assembly last week, and, after a hierarchical Divine Liturgy, sat in on a talk by Fr. Thomas Hopko. Even more blessed was I, however, when Fr. Basil told me last night after daily vespers that four of Fr. Tom's other talks have been put online in mp3 format, available for streaming listening and/or download!
What I've listened to so far is classic Fr. Tom (read: that means real, real good), and it can all be found here, thanks to St. John the Wonderworker in Atlanta.
