yeah, all shows are on the kool archives.
I think what i like about those djs i named is that they do something a lot of oldskool djs dont, which is play the tunes in an original style. I find that a lot of people on the radio these days present oldskool in full awareness of how old the music is and with a sense that they're revisiting the past - they do things like ID every track, give little insights about a tune or a label, let tunes play to the end, or do only the shortest of mixes towards the end, endlessly rewind every 'classic' tune, asking "who remembers this one" all the time - some how it feels a bit educational, sentimental and casual, and it makes the music feel tired.
By contrast the oldskool radio djs I like to hear most can play the records as if they were new+relevant, dont talk too much, get immediately headdown in the mix, do long and thought out mixes, dig deep in the bag for tunes that wouldve been played then but dont get played now, and bring energy and urgency to proceedings.
Its not easy to do: the audience often has heard these tunes for twenty years and the dj definitely has, so its only natural that the attitude with which they get played changes, but it can be done in a way that still feels exciting. Thats why old radio tapes are still of value <the tunes get played 'properly' and the selection is deeper and the sense of excitement about the music is palpable. Its funny why its so hard to recreate the same feel of an old recorded show from BITD now - I particularly rate the djs who try.
ETA: BITD Djs didnt have to answer the phone, look at tweets and interact with the chat room, they could concentrate on playing tunes - thats one key reason that it often doesn't feel as good to me - putting a record on is 5th in a list of other things to do. If stations want that interactivity then get an MC in to do it, and leave the DJ in peace to concentrate IMO
