Yes, here is link to a translation of the welsh legends, however, it is better to read them in their original form,(Welsh Prose) though it is a hard read! This is easier.
I know that Tolkien did not forsake these works, although many have argued that these were tainted by the time they were translated. Look for the link to Taliesin on the right near the bottom.

Another earlier version of the tale, more often compared to Irish folk tales:
Taliesin and Cerridwen
