Answer by taking a quote from the following article:

Mental As Anything are an Australian new wave/pop rock band that formed in Sydney in 1976. Its most popular line-up (which lasted from 1977-1999) was Martin Plaza (birth name Martin Murphy) on vocals and guitar; Reg Mombassa (birth name Chris O'Doherty) on lead guitar and vocals; his brother Peter "Yoga Dog" O'Doherty on bass guitar and vocals; Wayne de Lisle (birth name David Twohill) on drums; and Andrew "Greedy" Smith on vocals, keyboards and harmonica.

During the sabbatical, Mental As Anything still played short tours and one off gigs, but by 1993 they were back on record, providing the song "Ride", produced by Tim Farriss, for the soundtrack to the Yahoo Serious film Reckless Kelly. They released a compilation of rare album tracks and b-sides, Chemical Travel, in November.  By mid-1994 the band had recorded an album's worth of self-produced material but were having difficulty getting a release deal. They self-released an EP of songs, Bicycle, and gave it away on their summer 1994/95 tour of NSW and Queensland. Radio station Triple J received a copy of the Bicycle EP on Christmas Day 1994 and put the lead track "Mr Natural" on immediate heavy rotation. Other stations followed and the demand led to the track being given a commercial release as a single and reaching the top 30 on the ARIA Charts (although charting higher in the States where the tour and free EP didn't reach). The resulting album, 1995's Liar, Liar Pants on Fire, reached the top 40, with Mombassa's cover taking the 'Best Cover Art' award at the 1996 ARIA Music Awards.  Three further singles were lifted off Liar Liar in 1995 and 1996: Mombassa's "Nigel" which just failed to chart, a cover of Wreckless Eric's "Whole Wide World" which landed just out of the Top 50 (Top 30 in Victoria) and O'Doherty's tribute to Ms Faithful, "Marianne", which was released as the band supported Chris Issak on his 1996 tour of Australia.  On 16 August 1997, Mental As Anything celebrated 20 years together with the same line-up with a free birthday show at the Hopetoun Hotel in Sydney. Late 1997 saw the band put together their third group art exhibition, Mentals III, which was opened by former Prime Minister, Gough Whitlam, at the Manly Art Gallery (Paul Keating had opened their second group exhibition in 1990). Their 21st anniversary in 1998 was marked with the release of the last album by this line-up, Garage, which did not reach the top 50, nor did the two singles lifted from it, "Just My Luck" and "Calling Colin". December 1999 saw the release of Best of Mental As Anything which was accredited by ARIA with a gold certificate by 2001, and a seasonal single "White Christmas", that was given away at their "Yule Party" gig at Sydney's Metro Theatre.

Did they have any other successful songs?
The resulting album, 1995's Liar, Liar Pants on Fire, reached the top 40, with Mombassa's cover taking the 'Best Cover Art' award at the 1996 ARIA Music Awards.
