Mairi's Wedding

Can someone double check for me that Mairi's Wedding is now in Public Domain. It was written by John Roderick Bannerman (18651938) so, from my understanding of the law,we are now just beyond the 70 year copyright limit post the death of the composer. If I've got that correctthen I may get a recording of it done today or tomorrow on my Sow Hogfiddle to test out a new mic'

Thanks
