“Long live the Cuban revolution! Long live Comrade Fidel Castro!”

Phrase used by members of the Indian independence movement, which did not actually originate with Singh. In a Letter published in The Tribune (25 December 1929) http://naxalrevolution.wordpress.com/2007/03/23/bhagat-singh-on-the-slogan-of-‘long-live-revolution’/, Singh stated:
We are not the originators of this cry. The same cry had been used in Russain revolutionary movement. Upton Sinclair, the well known socialist writer, has, in his recent novels Boston and Oil, used this cry through some of the anarchist revolutionary characters. The phrase never means that the sanguinary strife should ever continue, or that nothing should ever be stationary even for a short while. By long usage this cry achieves a significance which may not be quite justifiable from the grammatical or the etymological point of view, but nevertheless we cannot abstract from that the association of ideas connected with that.
All such shouts denote a general sense which is partly acquired and partly inherent in them. For instance, when we shout “Long Live Jatin Das”, we cannot and do not mean thereby that Das should Physically be alive. What we mean by that shout is that the noble ideal of his life, the indomitable spirit which enabled that great martyr to bear such untold suffering and to make the extreme sacrifice for that we may show the same unfailing courage in persuance of our ideal. It is that spirit that we allude to.

Final address (1973)
Context: The people must defend themselves, but they must not sacrifice themselves. The people must not let themselves be destroyed or riddled with bullets, but they cannot be humiliated either.
Workers of my country, I have faith in Chile and its destiny. Other men will overcome this dark and bitter moment when treason seeks to prevail. Keep in mind that, much sooner than later, great avenues will again be opened, through which will pass the free man, to construct a better society.
Long live Chile! Long live the people! Long live the workers!
These are my last words, and I am certain that my sacrifice will not be in vain, I am certain that, at the very least, it will be a moral lesson that will punish felony, cowardice, and treason.

Vive Montreal; Vive le Québec! Vive le Québec libre!
From a balcony at Montreal City Hall, with particular emphasis on the word 'libre'. The phrase, a slogan used by Quebecers who favoured Quebec sovereignty, and de Gaulle's use of it, was seen by them as lending his tacit support to the movement. The speech sparked a diplomatic incident with Canada's government, and was condemned by Prime Minister Lester B. Pearson, saying that "Canadians do not need to be liberated."
