Originally released in 1968 by fledgling UK indie label Track Records for the European market only, this compilation of five single sides plus various album cuts became an instant hit on both sides of the Atlantic. Utilizing the original monaural mixes throughout, Classic's recreated one of the most sought after collector's items in classic rock. Rare mono masters of hits such as "I Can See For Miles", "Substitute", "Happy Jack", "I'm A Boy" and "Pictures of Lily" never sounded so good. Cut from the original full-track Mono takes on Classic's all-tube Mono cutting system.
