Delete a hole lyric line

Is it possible to delete a hole lyric line from a song? (or hide)
I have a song whit six lyric lines. Now I want to made a version whit only three lines (1, 2 and 6). How can I delete the others?
Ok I can delete each syllable in each line. There is not so al long song, but maybe there is a comfortable solution?

In write mode, select galley view, and un-zoom. Then you can marquee select the three lines you want to delete !
