Groggy mayles on rochelle concertina

[Keagan Beagan]

I've been trying to find some sort of sheet music to learn this song for awhile and I keep seeing videos of people learning it but I have no idea how they're learning the chords.  I got this pirate songs book on amazon that included the song inside but it was only the basic melody with no chords.  I also found a musescore version of the sheet music but it was clearly not made for concertina so I can't really learn it from there.  Does anyone know where I can learn this song?  It's from sea of thieves it's called groggy mayles.

Holy shit so upon further inspection I realized I'm a dumbass and didn't see the notes above the staff I was expecting a separate staff lol but I have one more question, what are the numbers above and below the staff?

The main man himself may well be along to comment! If you've got 'that' excellent book, then look for clues in the first few pages on how to decode the number system etc. It's pretty straightforward once you're used to it.

Wow I guess I accidentally skipped that page, thanks
