How Do Fleetwood Mac/Other Bands Split Profits for Record Sales and Such

[Musicman408]

Hey All:

Something that I am sure has been talked about in the past. When it comes to bands recording and selling music, how does Fleetwood Mac split up the profits? Since Stevie, Lindsey and Chris all wrote, the presumable earned more than Mick and John for playing, right? How would the split it up for each song? Or would they simply have a percentage split for the whole album?

Just curious!!!
