Sinitta was both Simon Cowell's and Fanfare Records' first signing. Cowell had contacted record producer and songwriter George Hargreaves who in turn provided the song, "So Macho". Armed with a highly infectious pop record, Sinitta looked poised for success; however, Iain Burton changed his mind and called Cowell to advise that he was pulling the plug on Fanfare Records. Convinced that "So Macho" was destined to be a hit, Cowell persuaded Burton to give him £5,000 to release the record.

The single was first released in late July 1985 and like Sinitta's début single, "Cruising" it quickly gained popularity in the gay clubs and on the Hi-NRG dance scene. Although the single failed to chart it continued to sell throughout the summer including 15,000 copies on import. The song's popularity led Cowell to make the decision to delete the single at the end of October 1985 in order to let demand build up again. As Christmas approached, the song found renewed popularity in straight clubs and discos. The single was re-released as a double A-side with "Cruising" on 17 February 1986, but was not an immediate success as it remained in the lower reaches of the charts. It was not until four months later that the single started gaining airplay and entered the top 40, upon which it quickly rose to number two in the UK Singles Chart. It was certified gold by the BPI, and has sold 585,000 copies. Iain Burton's initial £5,000 investment became a profit of £1,000,000 and paved the way for Fanfare's future.
