Singer/actress Fiona Kennedy (“Tartan TV”) leads a group of singers in HIGHLAND HEARTBEAT, a new music special that celebrates Scotland’s culture in song, from traditional Scottish compositions like “Auld Lang Syne” and “Raise the Flag for Scotland (Lightly Swims the Swan)” to pop hits “Let the River Run” (Carly Simon) and “I’m Gonna Be (500 Miles)” (The Proclaimers). Plus, discover Scottish Gaelic ‘mouth music’ — traditional Scottish lilting that sounds like scat singing or fast rap.
