Times Quick Cryptic 2139 by Teazel

Today’s Quick Cryptic from Teazel is typically teazing with one or two tricky bits, including a couple of clever cryptic definitions. It helps to know your card games, operetta composers and South American geography, which I do – finishing in 5:08. I had a rare (for me) MER at 4D – was I right to twitch the eyebrows? Whatever, it was good fun. Thank-you Teazel. How did you all get on?
