A Big Night in with Darren Hayes Tour: A Big Night in with Darren Hayes Tour was the third tour undertaken by Australian singer-songwriter Darren Hayes as a solo artist.  The tour was undertaken to celebrate the release of Savage Garden's 10th anniversary greatest hits album.  The staging for the tour was simple, with a 'living room' feel, featuring a bar, dining area and wardrobe.  The show featured a great deal of audience participation, drawing on game shows, reality TV and internet dating.  Between songs, a male member of the audience was invited on to the stage where he was given a haircut and makeover by the tour's wardrobe staff.  Later, three women were invited on stage as potential 'dates', two being voted off by the audience via live text voting.  The winner was then introduced to the made-over male and the pair were served a candle lit dinner on stage, whilst Darren sang love ballads.  At the end of the show, the woman was given the choice of either "taking the bloke" or winning Geri Halliwell's mobile phone number, or alternatively Jason Donovan's home phone number for Australian performances, as a consolation prize.  The musical side of the show featured the greatest number of Savage Garden songs that Darren had performed since the demise of the group.  This served as a kind of farewell to these songs, as he has rarely revisited them since this tour.  During this tour he met keyboard player and producer Justin Shave, who has since gone on to become an ongoing musical collaborator with Hayes.  The DVD release of the tour, named "A Big Night in with Darren Hayes", was recorded in the Concert Hall of the Sydney Opera House in Sydney, Australia in July 2006.  The DVD was released in stores on 6 December 2006.  It contains the entire live show, as well as various bonus materials.

Hayes added an animated video for the song as a teaser on his official website, as well as his MySpace profile, on 9 April 2007.  he single failed to chart due to its ineligibility as a promotional release.

We Are Smug (album): We Are Smug is a collaborative studio album recorded by Australian singer-songwriter Darren Hayes and producer and songwriter Robert Conley under the pseudonym We Are Smug.  Originally intended as an anonymous secret side project for Hayes to experiment with new sounds, the album was given away for free for a limited period via digital download as a gift to fans on Hayes' birthday on 8 May 2009 but all free links have since been removed.  Hayes has recently said he intends to commercially release the album with a bonus song at some point in the future.  The album is an eclectic and experimental vehicle where Hayes adopted various personas and experimented with vocal delivery and genre in a way he had never done as a mainstream artist.  It is unique as a recording because Hayes shares vocal duties with Conley, sometimes swapping out the lead for backing vocals.  Hayes takes the lead on about half the album at varying times changing his voice, alternating between a high falsetto, a lower raspy tone, experimenting with hip hop and beach boys styled harmonies.

Popular (Darren Hayes song): "Popular" (stylized Pop!ular) is the first single released from Australian singer-songwriter Darren Hayes' second solo album, "The Tension and the Spark".  The lyrics are a tongue-in-cheek send-up of celebrities and wannabes.  The song reached the top of the "Billboard" Hot Dance Club Play chart in March 2005.  This was Hayes' first #1 on the US Dance chart, either as a solo artist or with his former group, Savage Garden.  A radio edit was made which omits the instrumental section after the second chorus and also adds several new drumbeats to the second verse.  A video was later released and it shows Darren Hayes (and two scantily clad models) visiting various landmarks in London.  A flash mob dance also takes place in one of the stations in London.

So Beautiful: "So Beautiful" is a pop song written by Australian singer-songwriter Darren Hayes and Robert Conley.  In 2005, the song was released as a single as a part of the promotion of the greatest hits album "", a band that Hayes was part of until their split in 2001.  Hayes was credited on the release as "Darren Hayes (of Savage Garden)".

Me, Myself and (I): "Me, Myself and (I)" is a song written by Australian singer-songwriter Darren Hayes and Justin Shave for Hayes' third solo album, "This Delicate Thing We've Made".  The song was confirmed as the album's second single on Hayes' official MySpace page in July 2007.  According to Hayes' official website, the track was co-written and produced on the second-to-last night of the album recording sessions.  The track failed to make the top 40 in the United Kingdom, debuting and peaking at #59 on 24 November 2007.  The single sleeve artwork bears a striking resemblance to Kraftwerk's "The Man-Machine" album sleeve, and is most likely an homage to the electronic music pioneers.
