Captain Martin Crieff, who died in 1941. Is that Captain Jack ?
An this man with the Beatles looks like Matt Smith.
Some of their songs don’t seem to make this any less creepy
-Run for your life
-Across the Universe
-I’ll follow the sun
-Martha my dear
EDIT : The John Barrowman picture is a manip, (stop wondering about it !) but the one’s with Matt Smith is real, Steven Moffat said about it “Is Matt a REAL time traveler? This photo is 100% real - uncanny resemblance isn’t it? Bloody hell!!! Clearly we’re going to make that episode!! Wonder what it will be like.”
