Opening the Sexual Boundaries Concert CD

The ballad version was originally sparked as an impromptu encore during the end of the concert on April 20 when Liew announced she had no more songs prepared, but opted to reprise one of her songs.

The studio ballad version was also released as a radio airplay single to promote the concert album.

The DVD release contained mostly the same tracklist as the CD version, with the noticeable exclusion of Jan Lamb's performance due to his contract with another record company.

Additions include the music videos for four new songs as bonus tracks.

The DVD version also contains karaoke functions with optional karaoke-style subtitles and vocal reduction (as with most concert DVD releases in Hong Kong).
