Query: Ruben Gonzalez a singer?

I couldn't believe the sleeve notes until I heard the record. The recordings were made in 1945 and 1947. Ruben Gonzalez is featured as a singer. I've heard better soud quality from the 40's but nevermind: the recordings are quite interesting because the music as it played in Cuba now really was created in that period. The record is really disappointing from the piano point of view and it should really be stated in the information Amazon gives about this record that RG doesn't touch a piano on this album.
