Peel precedent

[Sarah]

Referring to legendary, late British radio [DJ John] Peel, the case of the man playing vinyl at the wrong speed (ie. 33rpm at 45rpm or vice versa). [The Peel] [Precedent] is often invoked by DJs to excuse their own mistakes. Traditionally, there were three possible outcomes of such a mishap:

[Peelie] would stop the track about 30 seconds in, fluff a [jocular] apology and then play the track again at the correct speed
Peelie would let the track run to its conclusion, then admit his error (or ignorance - a lot of his vinyl had no indication of the correct speed) while arguing that it sounded good at the wrong speed anyway
In rare cases, Peelie would let the track run to its conclusion, argue that it sounded great at the wrong speed anyway, and then play the whole track again at the correct [rpm], inviting listeners to draw their own conclusions with regard to its quality.
