In November 1974, Harrison became the first ex-Beatle to tour North America when he began his 45-date Dark Horse Tour. The shows included guest spots by his band members Billy Preston and Tom Scott, and traditional and contemporary Indian music performed by "Ravi Shankar, Family and Friends". Despite numerous positive reviews, the consensus reaction to the tour was negative. Some fans found Shankar's significant presence to be a bizarre disappointment, and many were affronted by what Inglis described as Harrison's "sermonizing". Further, he reworked the lyrics to several Beatles songs, and his laryngitis-affected vocals led to some critics calling the tour "dark hoarse". The author Robert Rodriguez commented: "While the Dark Horse tour might be considered a noble failure, there were a number of fans who were tuned-in to what was being attempted. They went away ecstatic, conscious that they had just witnessed something so uplifting that it could never be repeated." Simon Leng called the tour "groundbreaking" and "revolutionary in its presentation of Indian Music".
