Mungo Jerry came to prominence in 1970 after their performance at the Hollywood Festival at Newcastle-under-Lyme, Staffordshire, on 23 May, which was their first gig under this name, alongside Black Sabbath, Traffic, Ginger Baker's Air Force, the Grateful Dead (their first performance in the UK) and José Feliciano. Their show was well received and the organisers asked them to perform again on the following day. The band's first single, "In the Summertime", the first maxi-single in the world, released on 22 May, entered the UK charts at No. 13 and the following week went straight to No. 1. Ray Dorset had to ask his boss for time off to do the UK TV Show "Top of the Pops".
