vertical spacing inside a \right-column

[Martin Tarenskeen]

Hi,

I am creating a header with something like

composer = \markup {
  \tiny
  \right-column {
    "Words and Music by:"
    "XXXX XXXXX,"
    "YYYY YYYYY,"
    "and ZZZZ ZZZZZ"
  }
}

What should I do if I want the lines inside the composer column to be 
vertically spaced closer to each other, so that the column takes less 
vertical space?
