On 29 March 1969 , she represented the United Kingdom in the Eurovision Song Contest performing the song " Boom Bang-a-Bang " , written by Peter Warne and Alan Moorhouse , the song chosen from a selection of six by viewers of her BBC1 variety series '' Happening for Lulu '' and on a special show hosted by Michael Aspel in which she performed all six one after another . One song , " I Ca n't Go On ... " , written by Elton John and Bernie Taupin , came last in the postcard vote but was later recorded by Cilla Black , Sandie Shaw , Polly Brown and Elton John himself as well as by Lulu . In Madrid , Lulu was accompanied by Sue and Sunny while the orchestra was conducted by Lulu 's musical director Johnny Harris . Lulu later recalled : " Boom Bang-a-Bang " won , though three other songs , from Spain , ( " Vivo cantando " by Salomé ) , the Netherlands , ( " De troubadour " by Lenny Kuhr ) and France , ( " Un jour , un enfant " by Frida Boccara ) tied with her on 18 votes each . The rules were subsequently altered to prevent such ties in future years , but the result caused Austria , Portugal , Norway , Sweden and Finland not to enter the 1970 contest . Lulu 's song came out the best in sales , with German , French , Spanish and Italian versions alongside the original English . Later she told John Peel ; " I know it 's a rotten song , but I won , so who cares ? I 'd have sung " Baa , Baa , Black Sheep " standing on my head if that 's what it took to win ... . I am just so glad I did n't finish second like all the other Brits before me , that would have been awful . " Despite her dislike it is her second biggest UK hit to date , reaching No. 2 on the chart in 1969
