It was a remake. Paul Merton brought several old scripts up to date which were written by Galton and Simpson originally. Hancock's Half Hour was broadcast on both and Radio.
Probably the best episode was the Blood Donor.
"You want a pint! That is nearly an armful"
I love Hancocks work, and Syd James of course who's character usually led 'the lad' astray!. Neither the Radio Ham nor Blood Donor feature Syd. These two episodes (originally radio plays) have entered British comedy folklaw, and were originally issued as a double A side LP. If i happen to mention my ham radio activities at work, im usually met with a cry of 'it is r raining not in tokyo'
Some older hams in the UK claimed Tony Hancock damaged the hobby with the radio ham episode, but anyone who is a fan knows that the premis is that anything his character got involved with he would invariably get wrong due to his own pomposity, or fail at due to Syds influence.
Incidentally, Im also a blood donor, and my wife worked for many years for the National Blood Service!
Sadly, Hancock went the way of many in the comedy business
