ABOUT ALFRED'S ULTIMATE VOCAL SING-ALONG SERIES Alfred's Ultimate Sing-Along books give you everything you need to sing with your favorite songs. Each songbook has the lyrics, music notation, and chords to eight great hits, with lyrics-only pages included. There are two versions of every song on the CD: a full-performance track with an amazing sound-alike recording, and a professional accompaniment track so you can sing along. When you use the CD in your Mac or Windows-based computer, the TNT (Tone 'N' Tempo) Changer lets you easily change the key and temp to individualize the playback for just your voice and style. Learn to sing along with eight classic disco songs!
