Umm--if I'm not mistaken Mr. Willett is British, and most likely pronounces "burps" without nearly as much of an "r" sound in it as most contemporary urban Americans would produce. Only in that case would it rhyme with "Schoeps."
The two big exceptions that I can think of are (a) the old-fashioned white mid-Southern U.S. accent--if you can imagine a Kentucky colonel or prosperous Georgia plantation owner saying the word "burps," again the "r" sound wouldn't be discernable (or "di-sön-a-ble") in that, and likewise (b) a Down-East Maine accent ("Bert and I ...").
--best regards, y'all
