Written and produced by Bernard Simon and Terry Holt.
Originally released as a 12\" DJ promo in 1991 on The Boogie Times label, \"Unity / Fireball\" was always considered a Suburban Base record as the track \"Unity\" was included on the \"Sub Base In Your Face LP\" in 1992, and \"Fireball\" was put on the \"Classic Subbase\" compilation in 1997. \"Fireball\" was also used throughout the \"Suburban Base: Sound Of The Phuture\" vinyl that featured megamixes by The Berserker and Danny Breaks.
The vinyl was officially issued by Suburban Base in 2002 as a promo only DJ repress.
