Knew that I could make it if I tried
Then when we retire we can write the Gospels
So they'll all talk about us when we have died
That's a bit of Jesus Christ Superstar, of course, from the Last Supper scene. This idea of the disciples themselves writing the Gospels is an old one. It is present, for example, in the ?mid-late second century Apocryphon of James (translation here):
... the twelve disciples were all sitting together and recalling what the Saviour had said to each one of them, whether in secret or openly, and putting it in books.
