In 1990, Eric Clapton performed 18 nights at one of his favorite venues - the famous Royal Albert Hall in London. During the 18 run of shows Clapton performed with three different line-ups: a rock band, a blues band, and an orchestra. Eric returned to the same venue in 1991 with the same three line -ups and played a further 24 shows. The huge undertaking of rehearsing for performances of three distinctly different genres was made even more challenging by the line-up for the rock shows varying from 4, 9 or 13 band members.
