'' The London Chuck Berry Sessions'' is a Chuck Berry album which was released in 1972 by Chess Records. Side one of the album consisted of studio recordings, while side two featured three extended live performances recorded at the Lanchester Arts Festival in Coventry, England. At the end of the live section, the recording includes the sounds of festival management trying in vain to get the audience to leave so that the next performers, Pink Floyd can take the stage; the crowd begins chanting "We want Chuck!"
"My Ding-a-Ling" was edited down to approximately 4 minutes for single release; it became Berry's first and, to date, only No. 1-charting recording in North America. - Wikipedia
