I've just discoverd a sub-site of the Learning and Teaching Scotland website dedicated to Scotland's songs. This sub-site gives quite a nice overview over and some background information about Caledonian songs and tunes, including sound bites. I could even find samples of Puirt-a-beul, i.e. mouthmusic, reminding me so much of last years mini workshop on Puirt-a-beul with Darren MacLean, offered as part of the Celtic Connections music festival
