Task: Question Answering
Input (English): Passage: Minogue's third album, Rhythm of Love was released in November 1990 and was described as "leaps and bounds more mature" than her previous albums. Her relationship with Michael Hutchence was also seen as part of her departure from her earlier persona. Its lead single, "Better the Devil You Know" peaked at number two in the UK and four in her native Australia. Rhythm of Love's second and fourth single, "Step Back in Time" and "Shocked" were both a top ten hit in the UK and Australia. She then embarked on the Rhythm of Love Tour in February 1991. Minogue's fourth album, Let's Get to It was released in October 1991 and reached number 15 on the UK Albums Chart. It was her first album to fail to reach the top ten. While the first single from the album, "Word Is Out", became her first single to miss the top ten of the UK Singles Chart, subsequent singles "If You Were with Me Now" and "Give Me Just a Little More Time" both reached the top five. In support of the album, she embarked on the Let's Get to It Tour in October. She later expressed her opinion that she was stifled by Stock, Aitken and Waterman, saying, "I was very much a puppet in the beginning. I was blinkered by my record company. I was unable to look left or right." Her first Greatest Hits album was released in August 1992. It reached number one in the United Kingdom and number three in Australia. The singles from the album, "What Kind of Fool" and her cover version of Kool & the Gang's "Celebration" both reached the top twenty of the UK Singles Chart. 
Question: What is the last name of the person who embarked on the Let's Get to It Tour?
