Lacco un po Matto
Lento va,
Il tempo, fredd-e grigio,
In un vestito che,
Bavero rialzato, copre la citta,
Strade, case, gatti neri,
Un'auto va,
Corre, frena i suoi pensieri,
Corre e va.
Scacchi tutti bianchi,
Tu regina nera del re,
Scacco, scacco, scacco un po matto
Scacchi tutti neri,
Tu re bianco dei doveri,
Scacco, scacco, scacco un pomatto.

And the most famous singer, Miyuki Nakajima
