I have bundled together all four of my song packs covering aspects of life in past times - Ancient Egypt, Celts and Romans, Vikings and Dinosaurs songs! 37 songs altogether.Each of the four song packs contains:* mp3 files of all the songs, with both vocal and piano backing tracks * a PDF of the music and lyrics * an illustrated PowerPoint of each song for use with digital projectors and whiteboards. The audio tracks, vocal and instrumental, are embedded in the PowerPoint - you just have to click
