You only have until March 23rd to ask John Legend to serenade you through Google Assistant. The tech giant has announced that it's ending the musician's Assistant cameo in a couple of weeks, almost a year after it first became available. Assistant only answers as Legend for a select number of queries, such as the weather forecast and specific ones specifically designed for him. He can sing you a happy birthday, for instance, and tell you his favorite type of music. For other inquiries, you'll have to be content with the default Assistant responses.
