Tonight's with Jade Wright TV.
ON Friday nights, BBC Four is all about the music.
Whether you love household names or are searching for a new act to champion, the channel serves up music in abundance and standards are always high.
Transatlantic Sessions (BBC Four, 8.30pm) is a showcase of pure quality, and tonight's collection of performers is all from the very top-drawer. Bluegrass musician Alison Krauss, blues singer Eric Bibb, multi-instrumentalist Sarah Jarosz and Gaelic singer Kathleen MacInnes are among the performers.
If you're the sort of person who plans their week around Later With Jools Holland and loves to put a CD on in the car that your passenger has never heard before, but instantly falls in love with, then Transatlantic Sessions should be the first thing you programme into your TV recorder.
The standards are always high and the performances perfect. What more could you want? ? IT'S entirely possible you have got through your life so far without ever hearing Sonny Rollins play the saxophone.
But it's possible to make your life instantly better by remedying this terrible state of affairs. Because, as legends go, he's among the biggest and best around.
In a night of TV worth staying in for, BBC Four goes Sonny crazy. Because this is the 82nd year in the extraordinary life of the greatest saxophone player in the world, and a fine time to pay tribute to an epic career.
Four decades ago, a documentary was made that showed Sonny at the peak of his powers. Now the man who made that piece of history, catches up with him again. Arena: Sonny Rollins - Beyond the Notes (BBC Four, 9pm) is built around the explosive energy of Sonny's 80th Birthday Concert, where legendary figures Roy Haynes, Jim Hall and Ornette Coleman join him to celebrate his journey so far, his music and its future for a new generation. ? FOR decades, Public Information Films left an indelible mark on the minds of millions.
Few readers of a certain age could forget Rolf Harris almost drowned by a bunch of kids in a learn-toswim campaign or cartoon couple Joe and Petunia waxing lyrical about the dangers of worn tyres and "sailing dinghies".
The ads may not have broken the bank, but they certainly got the message across as we see in The Mad Bad Ad Show (Channel 4, 10pm), the first of a new panel show taking an irreverent look at the world of advertising.
