<P> Donald Brackett, in his 2007 book Fleetwood Mac, 40 Years of Creative Chaos, discussed the album Mystery To Me and the song "Hypnotized" which he described as "a gentle yet compelling hit for Welch on this record". In discussing Fleetwood Mac's change in direction in 1972 and 1973, he describes their stylistic changes as being better received at concerts in the United States, as at the time Americans were more open to them than the British who were still in heavy demand for blues - oriented rock . Hal Horowitz describes the song as "the highlight of the Mystery to Me album, and undoubtedly one of Bob Welch's most fully realized songs for the band". </P> <P> In 1999 Bob Welch received an award from ASCAP recognizing 25 consecutive years of airplay for his compositions "Hypnotized" and "Sentimental Lady". </P> <Ul> <Li> Bob Welch--lead vocals, acoustic and electric guitar </Li> <Li> Bob Weston--electric guitar solo and rhythm, backing vocals </Li> <Li> Christine McVie--Hohner Pianet, keyboards, backing vocals </Li> <Li> John McVie--bass guitar </Li> <Li> Mick Fleetwood--drums </Li> </Ul> <Li> Bob Welch--lead vocals, acoustic and electric guitar </Li>
