I remember a story about a PanAm L1011-500 that set off on a 2-engine ferry from Mexico City (alt 7,000ft+) and one of the 'good engines' failed shortly after take-off. After a low-level circuit, it landed safely on one engine and the Captain kissed the good engine! 411A may be able to confirm this or consign it to the "mythology" section!
Certainly, I remember a sim session on the TriStar partly devoted to one-engine flying, fortunately never did it for real.
The B747-400 also flies on one engine -at below a certain low weight it will maintain altitude when clean and will make an approach with certain conditions -such as above the GS and very little power applied!
