Pianosaurus were a 1980s New York toy instrument band.  They self-released two live albums and also recorded a debut album, Groovy Neighborhood, for Rounder Records in 1986.  There’s a second album but it was never released.  I wonder if the tapes still exist because if they did they should release the album.  Hell, I’d even release it.  As far as I know there’s no ukuleles in it but hey, toy guitars, toy piano and toy drums – lets not get picky.
