I apologise if this has been answered before, but I couldn't find it in the forum index...

I'm planning to perform 2 Xmas songs I've worked on:
1. at a couple of low-key local Xmas music events (unpaid)
2. possibly on local radio.

Song 1 is a poem by Robert Louis Stevenson (so in public domain), but recorded as a song by Sting (his melody) - I've used Sting's melody but slightly adapted it.

Song 2 is a poem by a contemporary poet that I've made into a song (melody is my composition).

I won't be recording either of them or playing them at paid gigs.

Do I need to get permission from anyone to perform them on either at the events or on radio?

thanks :)
