Radio superstar crooner the legendary Rudy Vallee attended the Valentino Memorial from the early 1980's through his last appearance in 1985. He died just a month prior to the 1986 Valentino Memorial, however his widow came and was honored in his memory.
One of the big errors in publications and thus, in turn all over the internet is that Rudy Vallee sang the 1926 Valentino tribute song "There's A New Star In Heaven To-Night". He never sang or recorded the song.
However he was fond of Rudolph Valentino although it's doubtful he ever met Valentino.
Here is a photograph of Rudy Vallee addressing the Valentino Memorial in 1984
