"Psycho Man" is a single by heavy metal band Black Sabbath.  It was originally released on the "Reunion" album in 1998, and was the first of two new singles from the album, the other being "Selling My Soul."  The song reached number 3 on the U.S. Mainstream Rock chart.  The song was later included in Ozzy Osbourne's 2005 box set "Prince of Darkness".  The music and lyrics were written by singer Ozzy Osbourne and guitarist Tony Iommi.  Psycho Man and Selling My Soul are the only Black Sabbath songs to be credited just to these two members. Ozzfest is an annual festival tour of the United States and sometimes Europe (and for the first time Japan in 2013) featuring performances by many heavy metal and hard rock musical groups.  It was founded by Ozzy Osbourne and his wife Sharon Osbourne, both of whom also organise each yearly tour with their son Jack Osbourne.  The Ozzfest tour has featured bands of a variety of genres within heavy metal and hard rock, including alternative metal, thrash metal, industrial metal, metalcore, hardcore punk, deathcore, nu metal, death metal, post-hardcore, gothic metal and black metal.

Curt Smith (born 24 June 1961) is an English musician.  He is best known for forming the band Tears for Fears, along with childhood friend Roland Orzabal.  As a solo artist, he has released four solo albums. "Over the Mountain" is the opening track of heavy metal musician Ozzy Osbourne's album "Diary of a Madman".
