This is one of the only music he can play for the moment, he never took piano lessons, he learned by himself with the help of videos on youtube.
There are many good piano tutorials on YouTube. He can learn to play a lot of songs with the help of the YouTube videos.
I wish good luck and the best to him.
Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
Thank you
