I was at a 50th birthday a few weeks ago, my mate got one of the other lads to dj, marquee job and bar in garden, about 100 people, blah blah.... Anyway the guy did a three hour set throughout the night and had everybody up dancing and thoroughly enjoyed themselves, the birthday boy congratulated him at the end of the night for a top set of tunes during the evening and asked him to make a playlist as he really liked some of the more underplayed stuff played.... His face was a picture when the lad confessed he had used the guy's own record collection throughout the entire evening, with the guys wife's permission, playing album tracks, b sides and those forgotten sounds that you really don't hear anymore.... Priceless....
