Task: Question Generation
Input (English): Passage: Morrison and EMI producer Norman Smith negotiated Pink Floyd's first recording contract, and as part of the deal, the band agreed to record their first album at EMI Studios in London. Mason recalled that the sessions were trouble-free. Smith disagreed, stating that Barrett was unresponsive to his suggestions and constructive criticism. EMI-Columbia released The Piper at the Gates of Dawn in August 1967. The album peaked at number 6, spending 14 weeks on the UK charts. One month later, it was released under the Tower Records label. Pink Floyd continued to draw large crowds at the UFO Club; however, Barrett's mental breakdown was by then causing serious concern. The group initially hoped that his erratic behaviour would be a passing phase, but some were less optimistic, including Jenner and his assistant, June Child, who commented: "I found [Barrett] in the dressing room and he was so ... gone. Roger Waters and I got him on his feet, [and] we got him out to the stage ... The band started to play and Syd just stood there. He had his guitar around his neck and his arms just hanging down".Forced to cancel Pink Floyd's appearance at the prestigious National Jazz and Blues Festival, as well as several other shows, King informed the music press that Barrett was suffering from nervous exhaustion. Waters arranged a meeting with psychiatrist R. D. Laing, and though Waters personally drove Barrett to the appointment, Barrett refused to come out of the car. A stay in Formentera with Sam Hutt, a doctor well established in the underground music scene, led to no visible improvement. The band followed a few concert dates in Europe during September with their first tour of the US in October. As the US tour went on, Barrett's condition grew steadily worse. During appearances on the Dick Clark and Pat Boone shows in November, Barrett confounded his hosts by not responding to questions and staring off into space. He refused to move his lips when it came time to mime "See Emily Play" on Boone's show. After these embarrassing episodes, King ended their US visit and immediately sent them home to London. Soon after their return, they supported Jimi Hendrix during a tour of England; however, Barrett's depression worsened as the tour continued, reaching a crisis point in December, when the band responded by adding a new member to their line-up.
Output (English): What were the names of the two people who were less optimistic about Barrett's erratic behavior?
