The same thing happened to me as a college DJ. I had to do a lunchtime "soft rock" shift. I hated the idea so brought my out records (as usual for most shifts, 'cept the Canadian opera.) This was around '84, so I brought along R.E.M., played a slow X song, symphonic version of a Sex Pistols song (stick it to the program manager!), and assorted other "college radio" songs & such that weren't overly aggressive but not traditional "soft rock." I ended up being about 5 minutes short, so I look through the station's LPs. "Okay, I'll throw the concept a bone and play some James Taylor. Let's see, oh gawd not 'Fire & Rain"...hmm, maybe this 'Steamroller' cut."
Boy was I surprised. Never imagined he had such a potty mouth.
It was definitely a revelation!!!!!
