Tenor v 5 String Banjo

I'm getting to grips with the finger board on my new tenor banjo and following some of the exercises in Gerry O'Connor's book Irish Tenor Banjo. One of the first tunes he looks at is The Wild Rover and I've been working on getting my little pinky finger into action as I don't use it that often playing the 5 string.
Here's the tune on the tenor and on the 5 string as a comparison.
