What if you happen to work for a guy whos been a radio DJ for about 20 years, has been in big markets like Chicago in the 80s, has a box full of tapes of airchecks from stations he's been on, all tapes that came straight out of the studio feed? Would you approach him and ask for the tapes? Give a price for them? Ask if I could borrow them to record, or is that rude? It's just sitting in the back of the warehouse on top of other boxes collecting dust.
