How do you create a medley of songs

[Garry A. Leslie]

Hello All,
I take it we are all talking about editing commercially available CDG's.
I have searched for a program/software to edit CDG files, either to add new lyrics, put in an introductory verse or chop some long winded musical interlude or ending, or make a medley.
It doesn't appear to exist.
KHPro seems to be the only way to create your own CDG but it is long winded.
Try www.audiotoolsdirect.com they list a lot of programmes, including MTU, for converting between formats, most are shareware, some are freeware, most have a trial period to try out the programmes, some obviously limit functionability (Is there such a word?)
Regards from across the pond.
