Wow, I have loved John Michael Talbot's music for over 20 years (Way before I was Catholic)- Actually for probably 15 of those years I didn't even realize he was Catholic. You would have thought the monks robe he was wearing would have given it away LOL I guess I never paid attention to the CD cover art. I never knew his story or that at one period in his life he was very anti-Catholic. I found his Christian testimony on you tube and just all I can say is Wow!
The actual testimony starts in segment 1/5 at the 5 minute mark. It is 5 segments and is therefore relatively long but it is well worth a listen.
