I found a wonderful resource of old interpreting tapes on Youtube. They are probably from the 70s and a little slow paced, but they have great practice exercises (starting around 2b). Also, you will get to hear Nishiyama Sen-sensei around 30a, so that is exciting. If you don’t know that name, you really should. He is basically the father of J<>E simultaneous interpreting.
Enjoy!
