The group began 1970 by appearing on the BBC 's review of the '60s music scene , '' Pop Go The Sixties '' , performing " Apache " and backing Richard on " Bachelor Boy " , broadcast across Europe and BBC1 , on 31 December 1969 . This was followed by Marvin and a reconstituted Shadows becoming resident guests on Richard 's debut TV series for the BBC , '' It 's Cliff Richard ! '' The group were chosen by BBC Head of Light Entertainment Bill Cotton to perform the Song for Europe in the 1975 Eurovision Song Contest . The Shadows recorded six songs , seen each week on a weekly television show '' It 's Lulu '' , on BBC1 and hosted by Lulu , a former Eurovision winner . The group taped all six performances in the TV studio before the series itself began , with the video cut into the weekly show . For the presentation of the songs on week seven and the announcement of the result on week eight , the pre-recorded performances were run again
