Wakeman called it "a day I will never forget for as long as I live". "Journey" also reached No. 3 in the US, and earned Wakeman an Ivor Novello Award The album went on to sell 14 million copies worldwide. On 27 July 1974, Wakeman headlined the Crystal Palace Park Garden Party concert, performing selections from "Six Wives" and "Journey" in its entirety with an orchestra, choir, and his band. By this time, Wakeman's health deteriorated. Excessive alcohol consumption, lack of sleep the five days prior to the show, and a wrist injury due to a fall led to a doctor treating him with morphine to help him through the gig. Soon after the show, he suffered a minor heart attack. During his recovery at Wexham Park Hospital, he wrote "The Last Battle", the first song for his new concept album, "The Myths and Legends of King Arthur and the Knights of the Round Table". Despite being advised to reduce his workload and improve his health, Wakeman continued with his career and to smoke and drink. He began a 20-date North American tour in September 1974 with the National Philharmonic Orchestra, the Choir of America, and his rock band. As per doctors orders, Wakeman was required to pass a heart monitor test before each performance. Wakeman later revealed that the tour cost him £125,000. In January 1975, Wakeman finished recording "King Arthur" at Morgan Studios with the New World Orchestra, English Chamber Choir, and the Nottingham Festival Vocal Group. Based on the stories about King Arthur and related figures, its release in April 1975 was a commercial success, reaching No. 2 in the UK and No. 21 in the US. It also earned Gold certifications in Brazil, Japan, and Australia. The album was promoted with three sold out shows at Wembley Arena in May 1975 with Wakeman performing the album with an orchestra, choir, and his rock band to a total of 27,000 people. As the arena floor was already set up as an ice rink for a different attraction, Wakeman chose to present the show as an ice pageant with fourteen ice skaters and the musicians' stage placed in the round and decorated as a castle. The shows, though well received and contributed to the album's commercial success, were expensive to produce. In 2009, the concerts came in at No. 79 on the "100 Greatest Shocking Moments in Rock and Roll" program broadcast on VH1.
