Collection of 14 songs performed in Cantonese, "Song Book" by award-winning vocalist Roger Chung featuring Jezrael Lucero on keys is a selection of jazzed up cantopop standards from the period 1981-2002. This Hong Kong Song Book concept is inspired by the Great American Song Book, which is an unofficial collection of songs from Broadway musicals, Hollywood movies and classic tunes popular on the radio, such as Somewhere Over the Rainbow (from The Wizard of Oz).

First of it's kind in Hong Kong, and one of the very few in the world, "Song Book" is a vocal-piano jazz duo concept album which has been descried by Hong Kong's own grandmaster of audiophile production Clarence Chang as "instantly creating history." These cantopop standards are performed in a style that is reminiscent of the classic Tony Bennett/Bill Evans vocal-piano duo album released in 1975, the 40s-60s supper club lounge shows and speakeasy jazz bars.
