[1] In 1973 Van Morrison and the Caledonia Soul Orchestra went on a three-month tour of the United States and Europe, the result of which was the live double album It's Too Late to Stop Now.
In live performances with the Caledonia Soul Orchestra, he would close the concert with a lengthened version of the Astral Weeks song "Cyprus Avenue" and then shout out "It's too late to stop now!"
The tour began with warm up shows at the Lions Share in Marin County, California, and an appearance on Don Kirshner's Rock Concert in April 1973 culminating with two nights at London's Rainbow Theatre in July 1973 (voted by Q Magazine readers as one of the top 100 live performances of all time).
By tour's end it featured forty songs with twelve of them covers such as Sam Cooke's "Bring it on Home to Me" and Sonny Boy Williamson's "Help Me".
John Collis in his book, Inarticulate Speech on the Heart, comments that "with the magnificent Caledonia Soul Orchestra on song he [Morrison] came of age as a magnetic stage performer, culminating in the release of the double set It's Too Late to Stop Now one of the most impressive of all attempts to squeeze the stage excitement of a rock performer on to vinyl.
