Can anyone shed any light on where these two photos of Colin come from, in which he's wearing his 6th Doctor waistcoat:

• https://www.alamy.com/colin-baker-actor-per0100-image5860168.html

The waistcoat means this post-dates the beginning of his time on Doctor Who (plus, he looks slightly older than he did in season 23), so it's presumably from the late 80s/early 90s. Elsewhere, commentors have suggested that it could be from a play, or a children's TV series called Cuckoo (though this has been disputed).

Any thoughts welcome! (But note that, as a picture-hosting platform, Alamy doesn't accept AI submissions, so to my knowledge they are real photos; commentors elsewhere also say that these pictures have been kicking around since before commercial AI image-generation was possible.)

Thank you
