How do I write the best performance by Sting in possessive form?

To write the possessive form of "the best performance by Sting," you add an apostrophe and an "s" at the end of "Sting." It then becomes "Sting's." For example:

- Sting's performance at the concert was unforgettable.

- Sting's latest album is full of great songs.

Note that the apostrophe comes before the s, even though "Sting" ends in a consonant. This is because "Sting" is considered a single proper name for this purpose, rather than being treated as the plural of the word "string."
