Ray Galton and Alan Simpson have been writing together for 60 years and given us classic comedies. If they never write another word we are all in their debt. Radio 2 had a good idea to celebrate their partnership by recreating some of their old scripts for today's new comedy stars. The last in the series was Paul Merton in the role Tony Hancock made famous, The Blood Donor.

Actually, it was written for Arthur Lowe so, in theory, it should have passed easily into another voice. Unfortunately, it didn't. Merton sounded as if he were reading. So did June Whitfield's daughter, Suzy Aitchison, playing the nurse, the role her mother took so memorably 48 years ago. Why? It wasn't the script or the players. It's the art of good comedy production that's gone missing. The technical process has grown easier. The making of words into magic remains a tricky art.

The final programme marking Galton and Simpson's 60-year writing partnership is a new version of one of their most famous works. Originally written for Tony Hancock, The Blood Donor is regarded as a comedy classic, so it's a brave man who would step into Hancock's shoes and take on what is pretty much a perfect piece of comedy writing.

Here Paul Merton takes the Hancock role and, despite seeming a little un-easy at times, comes about as close to anyone as carrying it off.

The script has been tweaked a bit to bring it up to date, but none of the memorable lines have been lost. And in an affectionate nod to the past, Suzi Aitchison takes the role of the nurse - a part played by her mother June Whitfield in the original 48 years ago.

This short comedy season, celebrating the 60-year writing partnership of Ray Galton and Alan Simpson by putting on a quartet of old scripts with new performers, ends on a bold note. Paul Merton recreates The Blood Donor, written for and performed by Tony Hancock in 1961, the classic where our self-important hero answers the call and gets a few surprises. It's bold of Merton to attempt this as, try as he may to present himself as a curmudgeon, everyone thinks he's a nice guy because, unlike Hancock, we feel we know his personality through panel games.

When Paul Merton performed in some rejigged Galton and Simpson comedies on ITV in the late 1990s, he did attempt some of the classic Hancock's Half Hour/Hancock episodes, but wisely steered clear of the classic Blood Donor. No such luck here, as possibly the most well-known episode of Tony Hancock's sitcom stars Merton in the last of this series of radio adaptations. All in all, it's been an odd series - the delivery and content often sounding antiquated and jarring with some of the contemporary updates.

Review of the I Tell You It's Burt Reynolds episode:

The family at the heart of this comedy drama are looking forward to watching The Great Escape together on the telly when someone hammers on the front door. It's Uncle Jim, and he's the most argumentative, obnoxious man imaginable. He's also played to perfection by Rik Mayall. June Whitfield is the deaf and slightly loopy grandmother who gets some great throwaway lines from writers Galton and Simpson: "Who's that with their arm round Gordon Brown?" she asks. It's David Attenborough cuddling a chimp in a TV ad. Uncle Jim, meanwhile, is certain he's spotted Burt Reynolds playing a bit part in The Great Escape and uses Radio Times to prove his point. Reynolds is not listed: "Bloody silly magazine," he barks. I knew he was a wrong 'un from the way he knocked on that door.
