Wow! Rick Wakeman's first show in the US. Fragile would not be released
in the US until January of 1972, but a number of songs from Fragile
were played this night at the Whisky to the amazement of the crowd.
Yes opened the concert with Roundabout and Heart of the Sunrise had
people gasping for breath. When Yes had finished the first of two
sets some soul brothers who were there to see soul singer Mary Wells,
who was also on the bill, asked "What's the name of that group?" after
i replied Yes one of them said "Man They Is YES!"

In 1971 I saw Yes at the Whisky A Go Go (touring to support the recent release of 'Fragile'), and the opening act was Mary Wells. Truly bizarre.
