Focus formed in mid-1969 by keyboardist, vocalist, and flautist Thijs van Leer, who recruited bass guitarist Martijn Dresden and drummer Hans Cleuver after he met them at sessions for the Jazz and Poetry radio program in Hilversum, Netherlands. The three went on to start a new three-piece band initially known as Thijs van Leer and the Rebaptised, playing a set formed mostly of cover songs by Traffic and original material mostly written by van Leer. In November 1969, during rehearsals at the theatre where van Leer performed as part of Ramses Shaffy's theatre group, they were joined by guitarist Jan Akkerman of the rock band Brainbox after Shaffy invited him to play with the trio. Van Leer later recalled the first try out session: "Jan came in and we jammed for hours, and it was really kicking". They then settled on the name Focus for the new band; Akkerman later said, "Focus is a Latin word that is the same in many languages. It means concentration, which is the meaning of what Focus does". Their first live gig as Focus followed at the Bird's Club in Rembrandtplein, and they soon secured a weekly residency playing two shows a night on two days. Early sets were mainly formed of covers, including "I Shall Be Released" by Bob Dylan, "A Whiter Shade of Pale" by Procol Harum and "Nights in White Satin" by The Moody Blues, mixed with original material, including van Leer's first song written with the group in mind, the instrumental "Focus".  In their search for more work and a steady income, Focus was chosen to play as part of the pit band for the Dutch production of the rock musical Hair produced by Welsh actor Victor Spinetti. They were invited to audition at the Victoria Ballroom, London after Dutch lyricist Lennaert Nijgh suggested them to Del Newman, the musical's director. Cast member Robin Lent claimed the production was suffering and Focus, taking part only for the money, "were also pretty rusty ... but this changed and everybody got into it". The show, launched in December 1969, involved six nightly performances a week and gave them space to rehearse in the afternoons for free and store their equipment. An album of the soundtrack featuring the band was recorded in February 1970 and released soon after by Polydor Records.  After Hair ended its run in June 1970, Focus declined an offer to tour the musical across the Netherlands for a year and a half and become a full time band. They had picked up more local gigs and dates across the country by this time, and had performed their first international gigs in Belgium and Spain. Their weekly earnings from gigs, plus their earnings from Hair, had reached 400 guilders though Akkerman recalled the group failed to appreciate its value and were quick to spend it. To manage their finances more carefully, Cleuver was chosen to oversee their earnings and expenses.
