album included Neil Diamond's "Kentucky Woman", which cracked the Top 40 in both the US (No. 38 on the Billboard chart) and Canada (No. 21 on the RPM chart), though sales for the album were not as strong (No. 54 in US, No. 48 in Canada). The Book of Taliesyn would not be released in the band's home country until the following year and, like its predecessor, it failed to have much impact in the UK Albums Chart. Early in 1969, the band released the non-album single "Emmaretta", named after Emmaretta Marks, then a cast member of the musical Hair, whom Evans was trying to seduce. By March of that year, the band had completed recording for their third album, Deep Purple. The album included the track "April", which featured strings and woodwind, showcasing Lord's classical antecedents such as Bach and Rimsky-Korsakov. This would be the last recording by Deep Purple Mark I. Deep Purple's North American record label, Tetragrammaton, delayed production of the Deep Purple album until after the band's 1969 American tour ended. This, as well as lackluster promotion by the nearly broke label, caused the album to sell poorly, finishing well out of the Billboard Top 100. Soon after Deep Purple was finally released in late June 1969, Tetragrammaton went out of business, leaving the band with no money and an uncertain future (Tetragrammaton's assets were eventually assumed by Warner Bros. Records, who would release Deep Purple's records in the US throughout the 1970s). During the 1969 American tour, Lord and Blackmore met with Paice to discuss their desire to progress the heavy rock side of the band further. Having decided that Evans and Simper would not fit well with the style they envisioned, both were replaced that summer. Paice stated, "A change had to come. If they hadn't left, the band would have totally disintegrated." Both Simper and Blackmore noted that Rod Evans already had one foot out of the door. Simper said that Evans had met a girl in Hollywood and had eyes on being an actor, while Blackmore explained, "Rod just wanted to go to America and live in America." Evans and Simper would go on to co-form the bands Captain Beyond and Warhorse respectively.
