Go the Mechanical Copyright Society site here where you can get all the info you need. There is even an online form to fill in, they will then charge you for the use of any copyright songs tunes on your CD by number of songs/tunes and number of CDs you intend to produce. My morris side Aldbury have just produced a CD with 8 copyright tracks on it and ~200 sales predicted and it cost us something like £25 for a licence. That way the copyright owners get what they deserve and you are above litigation.
