Congratulations by Cliff Richard

Here's some trivia from the Congratulations Songfacts. "Congratulations" is the longest single-word title and is also the longest (legitimate) word to appear in the title of an UK chart-topper. John Paul Jones, later of Led Zeppelin, played bass guitar on this. This came in #2 in the 1968 Eurovision Song Contest.
