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.

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.
