S970 - best method to write words to appear on score. Help please.

[Taffinator]

Apologies if this has been raised previously, if so please point me in the right direction.

I've recorded a midi song & want to sing along with it, so I'd like to be able to print some words to be seen as the score progresses in the viewer.

This would also help a friend who will play sax during parts of the song.

Any guidance greatly appreciated,

Mike
