Jeffrey Gibson recently made available a whole bunch of audio recordings of George Caird's lectures. I uploaded these to my webspace, and Matthew Montonini indexed them (See George Caird's New Testament Theology Lectures Online).Jeffrey has now dug out another fifteen lectures, this time on the epistles to the Romans and the Synoptic Problem, and dating from 1983. I have uploaded them (Raw indexing here) and Matthew has added links here:

Matthew also blogs on this here.
