Not a dunce! I had to find out a couple of years ago. It's a complicated one as a lot of amateur companies do the 'songs from the shows' type things to fund raise, without paying any rights, under the impression that you can do a % of a show without buying the rights. This isn't the case. It all depends on *how* they're being performed. The legal position is that you can sing songs from shows, or even sing and dance songs from shows, without paying rights as long as you are not performing them as though they were in the show. So for eg. you could have the cast sing and dance to a number from Wicked, but if you dressed them all in green and added a nominal 'Elphaba' or 'Glinda' then you would have to pay for rights... (which of course you can't do for Wicked as it's not available for licensing, but you get the gist!!) Does that make sense!? Basically, if you want to perform a song from a musical as it would be performed in the actual musical then you have to contact the rights holders for rights. When we did Grease we bought the rights to extra songs (this has changed since, I know) and it was about £15 per song per performance so it wasn't a great deal. Hope that helps! It's Friday and I'm a bit rambly! If it doesn't, let me know and I'll try again!
