The Bomber by the James Gang (1970). Wikipedia article here.
"On the initial pressing of Rides Again, a 90-second electric rendition of Boléro is interpolated into the song "The Bomber." However, Ravel's estate (which still owns copyright on the work) objected, and as a result the track was edited and that section was removed from the song on subsequent pressings of the album until the late 1970s. CD re-issues of Rides Again contain the full version of "The Bomber," with the "Boléro" section restored."- from Wikipedia article
The Boléro piece starts at the 3:28 mark.
See My Way by Blodwyn Pig (1970).
The Bolero beat (and full tribute) is from 3:10 to 3:50
The Knife by Genesis (1970). Wikipedia article here. The Bolero beat comes in at 7:15 and lasts until 7:52. Is this truly the Bolero beat - the first couple beats of each measure fits Bolero and then it's slightly different at the end of the measure. When does a beat no longer become considered the Bolero beat?
Abaddon's Bolero by Emerson Lake & Palmer (1972). Wikipedia article here.
"Abaddon's Bolero" sounds like a martialized Boléro (in 4/4 rhythm rather than the usual 3/4). A single melody containing multiple modulations within itself is repeated over and over in ever more thickly layered arrangements, starting from a quiet hammond organ making a flute-like sound over a snare drum, and building up to an ear-shattering wall of sound. This aspect may well be a nod to the similar effect in Maurice Ravel's famous Bolero. Abaddon's Bolero is very replete with overdubs. Almost every time another instrument comes in, it's another overdub." - from Wikipedia article.
Living On Your Own by Budgie. From the album "In for the Kill" (1974).
The Boléro starts at the 4:02 mark and continues until 5:56 and then again from 8:26 to 8:39. The longer Boléro section is actually a take on Beck's Bolero (see above for Beck's Bolero).
