The choral ensembles affiliated with the orchestra are the Dresden Philharmonic Choir and Dresden Philharmonic Chamber Choir. "Girl Anachronism" is a song by American dark cabaret duo The Dresden Dolls, released as a promo single from their self-titled debut album.  The lyrics, alternately angry, apologetic, and full of complaint, deal with Amanda Palmer, the band's lead singer, as a "problem child", a trait which she blames on the fact that she was born a few days premature, by Caesarean section.  As the song grows, the lyrics split into various subplots, all of which are related to feeling out of place or out of time. Amanda MacKinnon Gaiman Palmer ( ; born April 30, 1976), sometimes known as Amanda Fucking Palmer (AFP), is an American singer-songwriter who is the lead singer, pianist, and lyricist of the duo The Dresden Dolls.

Formed in 2000, the group consists of Amanda Palmer (lead vocals and piano; additional: keyboards, harmonica, ukulele) and Brian Viglione (drums and percussion; additional: guitar, bass guitar, backing vocals).  The two describe their style as "Brechtian punk cabaret", a phrase invented by Palmer because she was "terrified" that the press would invent a name that "would involve the word "gothic"".

"Sing" is the first single by The Dresden Dolls duo, taken from the second studio album "Yes, Virginia...".  It was never released in shops, only as a promo for radio stations.

Aside from being friends, members of the group have various connections with each other: Neil Gaiman and Amanda Palmer are married, and Ben Folds appeared on and produced Palmer's solo debut "Who Killed Amanda Palmer".  The band have been referred to as a supergroup, acknowledging that moniker by describing themselves as "tomorrow's supergroup today".  The musical members of 8in8 each have different styles and the EP "Nighty Night" was created to reflect each one, with main lyricist Gaiman adapting to suit.

It was originally released by Important Records Records in December 2003 in an edition of 500 on white vinyl.  The set also included a photograph signed by Amanda Palmer and Brian Viglione.  The 7" was later reissued in October 2005 on Palmer's own 8 Ft. Records during the band's Fall 2005 North American tour.  The cover of the reissue depicted a painting by Barnaby Whitfield that recreated the photo from the original release.
