THE DIAL-UP

Lewis is working a dead-end job on an internet helpline when he gets a call from Callum, whose lack of tech knowledge quickly reveals him to be a customer from 1999.

You need to be old enough to sing along to the internet dial-up tone to fully enjoy this audio sitcom, but if you are, then prepare for an entertaining barrage of cultural references that pre-date Facebook.

The lads discover they are sitting in the same spot – a block of flats that was knocked down after a fire in 1999 and replaced with offices.

You can guess what happens next but this perfectly formed fourepisode show is no less entertaining for that.
