I started in 1999/2000, getting hooked in 2000 with the One Big Belly Tour (anyone remember that?) plus the Saturday show which was amazing. Team was Dave, Will & Mel.
I used to have a radio and listen on the way home from 6th form, I remember the afternoon show getting longer. I eventually got a pocket DAB to listen
2003-2006 I listened less as I was at Uni (never up for the breakfast show) but listen again came in around '06 so I listened on that and when I started work later in '06 I used to listen on the way to work & then use listen again at work to listen tot he rest of the show, this carried on until 2012 basically.
Now I listen to the whole show on Tune in (3:30-7pm), the clocks change here on Sunday so its 4:30-8 so I'll probably turn off at 7 at the latest and use listen again the next day, when the UK clocks change it's 5:30-9 so I'll be getting more on listen again until March.
