Laney Brown, 8, suffered from leukemia.
Her dying wishes were to meet country music superstar Taylor Swift and for some people to come by her house for a night of caroling.
On Friday -- her birthday -- Laney and Swift video-chatted through FaceTime, a software application that allows callers to see each other on Apple products.
Then, Saturday night, the singers came. At first it was hundreds of people, then thousands. Then it was about 10,000, CNN affiliate WFMZ reported.
