The Merry Men of the Riverworld — John Gregory Betancourt

When an actor who played Robin Hood on a 1950s children's TV show wakes up in Riverworld, he decides to live out his dreams and forms a new band of Merry Men (including Abraham Lincoln as Little John). Unfortunately, he didn't count on running into Al Capone, who has hijacked a thriving technocracy run by Jules Verne... Set in Philip Jose Farmer's "Riverworld" universe, this story was written with Farmer's permission.
