Joseph has been an avid collector of vinyl records for most of his life, many of which were scavenged from his weekly visits to the Sungei Road Flea Market. With a special focus on Singapore music in the 1960s, he has a fondness for the creativity and rock ā€˜nā€™ roll spirit of that era, and has published three books that chronicle the events of that period including Legends of the Golden Venus and Apache over Singapore Part I and II.
