Hi Dave I have checked both sets of TAB the ( TEF & PDF ) against the on screen TAB and all seem accurate to what @BanjoBen explains in the lesson. I have also compared the MP3 file with the backup file that has the banjo present and it seems fine too.
The only thing I feel might be different is that Ben’s Melodic arrangement does sound different to a straight forward arrangement of this tune. Personally I prefer a straight forward arrangement of I am a Pilgrim without all the fancy melodic twiddle bits. But this lesson is about teaching Melodic Banjo. If you don’t like the way that Ben plays it that’s fine. Find a lick that you do like and switch it around Ben won’t mind, in fact I know he would encourage you to do so.
