Manteca just fits Robert Duchaine. The seasoned comedy veteran, who will be headlining a Deaf Puppy’s show on Saturday night at Strings, has visited before as a guest of Chris Teicheira and Anthony Krayenhagen, and fell in love with the working class feel of those who came out to support independent artists doing what it is that they love. So when Teicheira extended the invitation to have Duchaine return to Manteca – this time playing a room much more like an authentic comedy club than the wide-open expanses of the MRPS Hall he performed in his first time – it was a no-brainer.
