\fromproperty as instrument name

[Menu Jacques]

Hello folks,

I’d like to use the instrument name specified in the header as the actual 
instrument name:

%%%%%%%%%%
\version "2.19.39"

\header {
  instrument = "Premier"
}

% The score definition
\score {
  {
    \new Staff <<
      \set Staff.instrumentName = \markup{\fill-line{\fromproperty 
#'header:instrument}}

      \context Staff <<
        \context Voice = "PremierVoiceOne"
        {
          a b c d
        }
      >>
    >>
  }

  \layout {}
}
%%%%%%%%%%


But I get an error message on the next syntactical element, here \context 
Staff, see below.

Thanks for your help!

JM
