[Tex/LaTex] Remove section header from a beamer theme (Singapore)

beamerheader-footerthemes

I like everything about the beamer theme Singapore except:

  1. The centering of the frame title
  2. The navigation symbols that remain at the bottom
  3. The sections in the header

The first two are easily solved by

\setbeamertemplate{frametitle}[default][left]
\setbeamertemplate{navigation symbols}{}

I still can't find a solution for the third though. \setbeamertemplate{headline}{} gets rid of the sections in the header but dumps the nice shading. So my question: how do I get rid of those pesky sections (e.g., the "foo bar baz" below) in the header without dumping the shading?

A quick way disabling the navigation header containing the sections while keeping the shading:

\renewcommand{\insertnavigation}[1]{}

or

\def\insertnavigation#1{\relax}
