I didn’t know that! My mistake. I only know “Questions” from the BF box set, where it’s sequenced among unreleased out-takes from just before they split up.
I mean BS (Buffalo Springfield), not BF. Blame it on the Missing Proofreader. 
I was gonna do that same thing, BF, then realized it would be BS, didn’t want to blaspheme, and then went whole hog for “Springfield”
In Anthrax’s 1986ish rap-metal I’m the Man, you can a snippet from Metallica’s Master of Puppets. Given the general tone of the song, I think it’s both an homage and a joke.
KISS’ Destroyer album has a few actual samples: The introduction to Detroit Rock City starts with a news report of a teenager being killed in a car crash, then switches to the sounds of the teen getting into the car and driving away, then the radio comes on and it’s playing Rock And Roll All Nite from the Alive! album.
The album ends with an untitled sound montage containing samples of Great Expectations, the last song on side 1, and snippets of Paul Stanley’s stage banter from Alive.
Just to be clear; a sample is when you record part of a song and play it back as part of your song, looped or otherwise.
If you play a few notes or sing a line from another song in your song, that’s a quote. Not a sample.
My example was indeed a sample. It is Hetfield’s voice that you hear shouting “Master!” with the accompanying riff, all lifted from Metallica’s song.
Money’s drummer on the Can’t Hold Back album, Mike Baird, plays two measures of Led Zeppelin’s “When the Levee Breaks” during the bridge of “Take Me Home Tonight”. Might not count as a sample since Baird actually played the drum beats in the studio, though.
EDIT: reading upthread, I guess Baird is *quoting *LZ, then 
Monster Magnet’s Dave Wyndorf is a big fan of 1970s hard rock and psychedelia:

[li]“Dopes to Infinity” borrows the main guitar riff from “Woman Tamer” by Sir Lord Baltimore, and the chant “What can I say?” from Hawkwind’s “Lord of Light”.[/li][li]“Twin Earth” is a pretty close reworking of Captain Beyond’s “Mesmerization Eclipse”.[/li][li]“Evil (Is Going On)” is a note-for-note cover of Cactus’s arrangement of the same song (an old blues standard).[/li][li]The main guitar riff for “Bummer” is copped from Hawkwind’s “Time We Left This World Today”.[/li][/ul]
There are probably a few more I’m forgetting…
How do you know that’s what it is?
Yeah, it may not be as common as with hip hop but lots of rock/pop artists over the past couple of decades have sampled drum beats.
These two use Led Zep’s When the Levee Breaks:
Chapterhouse, Pearl
Sophie B Hawkins, Damn, I Wish I Was Your Lover
And this one uses Bobby Byrd’s Hot Pants
The Stone Roses, Fools Gold
Goldfinger’s cover of Duran Duran’s Rio segues into the guitar riff from Rainbow in the Dark by Dio and the lyrics change to
His name is Dio
Ronnie James Dio
His name is Dio
Ronnie James Dio
That’s what it sounds like. I don’t have a link to any quotes about it, or sheet music to refer to or anything like that, though.
Martin Mull’s "Licks Off of Records" samples “Day Tripper,” “Sunshine of Your Love,” and “Satisfaction” at the end.
and they change the song just before that so they are singing Rio over a Dio track, Now I want to hear that song.
