No Time Signature, bar lines...

I have a pair of "Amen" pieces I'm trying to typeset.
Being traditional church music, they have no time
signature - and the bar lengths are very odd,
the bars only being there to organise the piece and aid rehearsal.

So, on the first one the source I have come up with is this:

trebkend = \new Staff {
  \clef treble
  \relative c'' {
    << { a2 \bar "|" d1 } \\
    { \stemUp a2 \bar "|" a2 b2 } \\
    { g2 \bar "|" g1 } >>
  }
}

basskend = \new Staff {
  \clef bass
  \relative c {
    << { e2 \bar "|" d1 } \\
    { g,2 \bar "|" g1 } >>
  }
}

<<
  \trebkend
  \basskend
>>

Which comes out very unusually, and, crucially, with a time signature.
Can I turn this functionality off and still draw bar lines where I
want them without the dischordant notes being displayed on top of one
another - ie, so they are back-to-back as is usual for tone or semitone
intervals?

Thank you,
