Mental As Anything (or Mentals to fans) is an Australian New Wave–rock music band formed at an art school in Sydney in 1976. Its most popular line-up (which lasted from 1977-1999) was Martin Plaza (real name Martin Murphy) on vocals and guitar; Reg Mombassa (real name Chris O'Doherty) on lead guitar and vocals; his brother Peter "Yoga Dog" O'Doherty on bass guitar and vocals; Wayne "Bird" Delisle (real name David Twohill) on drums; and Andrew "Greedy" Smith on vocals, keyboards and harmonica. Their original hit songs were generated by Mombassa, O'Doherty, Plaza and Smith, either individually or collectively; they also hit the Australian charts with covers of songs by Roy Orbison, Elvis Presley and Chuck Berry.
Their top ten Australian singles are "If You Leave Me, Can I Come Too?" and "Too Many Times" (both from 1981), "Live it Up" (1985) and "Rock and Roll Music" (1988). Internationally, "Too Many Times" made the Canadian top 40 in 1982, and "Live it Up" peaked at No. 3 in UK, No. 4 in Norway, and No. 6 in Germany, after it featured in the 1986 Australian film "Crocodile" Dundee.
