A memory from April 2004: I was surprised to hear two songs in a row on KDHX's "Lotsa A Cappella" that featured instruments, including one song that had a lengthy instrumental interlude.
One of the substitute hosts explained, "They have such beautiful voices, so I don't think we should hold it against them that they use instruments."
In their defense, the tunes warranted the airtime. Besides, the show was called "Lotsa A Cappella," not "Only A Cappella," so technically, they were in the clear.
