A little advert...

Son-in-Law 2 is an actor with a group called The Showstoppers who do improvised humorous musicals. They're amazingly good - the audience suggests a title, a setting, a style of musical etc and they do genuinely improvise - singing, harmonising, rhyming and all.

They video all their shows - on one camera from the back of the theatre - but they've reworked a song from one show in a more finished state. (The rhymes in this are more varied than they would be in the improvised version but the general effect is much the same as it was originally.) It's about a lovelorn dentist. They asked various dentists in London whether they would lend their surgeries for the filming and one agreed.

Have a look: it only takes three minutes.

Son-in-Law 2 is the next patient. (These are not his real teeth.) The genuine dentist has a cameo role at the end, behind a magazine.

Should you by any chance be in Edinburgh just now, you could see them - they're appearing at the Fringe every night and also have children's matinees. And once they're back in London they do shows there and thereabout, as well as corporate events, weddings... .
