I think it only serves the band right if I start my posting with their very first song. Heeya (a girl’s name) was a hit song in 1985 (btw, I was born in 1985..). In the original Boohwal’s first album, this song was sung by Lee Seung-Chul. Below I provide a link of Lee Seung-Chul & Boohwal 2002 Concert. You can see the drummer Chae Jemin and bassist Seo Jae-Hyuck (both blond :p) sitting in line together with Lee Seung-Chul and gitarist/leader Kim Tae-Won in the beginning of the video.
This song was written and composed by Yang Hong-Seob (양홍섭).
The second video is Boohwal’s performance in Pentaport Rock Camp 2009, the incumbent vocalist Jeong Dong-Ha singing “OZ” and “heeya” in rock version. (He also sings “heeya” in the ballad version, but this is one exceptional performance which I like so much).
A little bit about the song “OZ”.. Released in the 12th album (part 1) in 2009. Composed by bassist Seo Jae-Hyuck and written by Se0 Jae-Hyuck and Jeong Dong-Ha. Check out the “12th Album” category for lyrics and translation~^^
