I saw this blog post and no other details are below it.
This was posted last May 26
The blog post was entitled うたのおじさん romanized as "Uta no Ojisan", translated as "Song of an old man"
I really wonder what is he going to release with this song?
There's no sample either~
There's a text below,
"Kyou wa utautai."
"Today I want to sing."
Come to think of it,
My sis dared me not to sing today.
I wonder if I can accomplish that.
