Inspiration/suggestions for a Blues piece (Piano level 3)

[EarlyInTheMorning]

DS age 9 will be doing his grade 3 exam in July. I'm saying this to give you an idea of where he's at.
I am looking for a piece of music that is lively like BarrelHouse Blues that I can buy from music notes. I would appreciate any suggestions please.

My DS (9) is just starting grade 3 pieces but he also has Jazz Up-Grade (1-2) which has a good selection of pieces that he is enjoying playing.

Musicroom are great for sheet music.

Look here for some digital down loads for Blues Piano. You will need to down load Sibelius Scorch (free) to view them (you can see the first page.) You can also alter the key if necessary.

Several I looked at were around the same level as Barrel House Blues.
