won the contest, which would become an international hit for Gall, and would have an influence on the type of songs entered into the contest in years to come. Ahead of the 1966 contest, the EBU invited broadcasters to submit proposals on ideas they believed should be introduced in future editions. This was prompted by concerns from CLT on their ability to stage the next event. Some ideas in common among several broadcasters included: the introduction of semi-finals to reduce the number of competing acts, with some also suggesting that competing countries should be split on a geographic or linguistic basis; music experts having a 50% stake in the result to enable more of an emphasis being placed on musical quality; and a tightening of the rules on language and submission cut-off, with the creation of an executive supervisor role in order to oversee the contest and raise production standards. Further proposals on changes to the contest included holding the event over multiple locations, with performances and hosting duties split across two or three different competing countries; this proposal was rejected following concerns raised that musical quality and consistency would suffer in a contest held across multiple locations and with multiple orchestras, and that the risk of technical failure would also increase by using multiple venues. The EBU went on to adopt a number of the suggestions raised, with the following contest featuring music experts in the national juries, and the implementation of a language rule stipulating that songs must be performed in one of the national languages of the participating country. Other changes, such as semi-finals and splitting countries by set criteria, would subsequently be revisited in decades to come. The Eurovision Song Contest 1966 was the eleventh edition of the contest, organised by CLT and held on 5 March 1966 at the Grand Auditorium de RTL, Villa Louvigny in Luxembourg City, Luxembourg. This marked Luxembourg's second contest as host broadcaster, using the same venue as that in 1961. This contest saw the first performance by a black artist at Eurovision, when Milly Scott represented the Netherlands. Udo Jürgens secured Austria's first win with "Merci, Chérie"; this was Jürgens' third attempt at victory, having previously finished 6th in 1964 and 4th in 1965. The Eurovision Song Contest 1967 was the twelfth edition of the contest, organised by Österreichischer Rundfunk (ORF) and held on 8 April 1967 at the Großer
