Sunny Day Service's best scorebook, including special interviews and song analysis. Sunny Day Service - Title: Sunny Day Service Best - ISBN: 978-4865640280 - Publisher: Rittor Music - Contents: Special interviews, song analysis, member-specific album introductions, secrets of playing style, instrument introductions, etc. I bought this book about 30 years ago, but it's in very good condition. It includes not only scores but also interviews with the members, such as their talks and thoughts on the songs.
