a rare excursion into vocals for a band known for instrumentals (although they had cut vocal tracks on most albums, plus some singles 'B' sides, and had four charting vocal singles in the '60s). Welch sang lead and let the world know when, forgetting a couple of words, he turned to colleagues and said "I knew it" in range of his microphone. Author and historian John Kennedy O'Connor notes in The Eurovision Song Contest – The Official History that they were not a popular choice to represent the UK and the viewers' postal vote was the lowest in 'Song For Europe' history. EMI however released a compilation album in 1976, spanning 1962 to 1970: Rarities with sleeve notes by John Friesen. The first half of the album was from Marvin's solo career and the second was by the Shadows. Following the rare vocal single "It'll Be Me, Babe", written and sung by Marvin & Farrar, John Farrar amicably left the band that year, moving to the US to become the music producer for Olivia Newton-John. Among her hits, Farrar wrote "You're the One That I Want" from the film Grease which was covered by the Shadows in 1979. The packaging of hits in Twenty Golden Greats by EMI in 1977, which led to a number one album prompted the group to re-form once more for a 'Twenty Golden Dates' tour around the UK, featuring Francis Monkman (formerly of Curved Air and soon to be in Sky) on keyboards and Alan Jones on bass guitar. Francis left after that tour and the line-up settled as Marvin, Welch and Bennett, supplemented on records and gigs by Cliff Hall (keyboards) and Alan Jones (bass). It was this line-up that reunited with Cliff Richard for two concerts at the London Palladium in March 1978. Highlights of the concert, including four solo Shadows tracks, were released the following year on the top ten charting album Thank You Very Much. On the back of this The Shadows recorded an instrumental version of "Don't cry for me Argentina" from the West End production "Evita", released as a single at the tail end of 1978. The record eventually reached number 5 in the singles chart thereby giving the group their first top ten single since the 1960s. In 1979, their version of "Cavatina" also became a top ten hit, and they recorded ten more tracks with bassist Jones
