Love both tracks. Move Over is probably one of my top 2 favorites by Janis.
I know amongst most Janis fans, they wouldn't care for a remake of it, but Cinderella did what I consider to be a great version on the late 80's CD "Stairway to Heaven / Highway to Hell", which had a number of 80's rockers doing remakes of songs by artists or bands that lost an artist due to substance abuse.
Great album btw:
9 times out of 10, I'd take Thorogood over Joplin, but in this case, I'm leaning towards Janis. I'm going to give both a good listen before deciding.
