Peak positions of PSB singles on the Cash Box charts

Although the Billboard magazine charts are the most widely recognized and cited sources for gauging the performance of pop music singles in the United States, they're by no means the only ones. In fact, for many years Billboard had a major rival in the form of Cash Box magazine, which published its own national record charts from 1950 until it ceased publication in late 1996. Elsewhere on this website I provide the peak positions of all of the Pet Shop Boys on the Billboard singles chart, but here I'm listing just those PSB singles that also appeared on the Cash Box chart, along with the corresponding Billboard peak placement provided as well for comparative purposes. That comparison yields mixed results—with some singles performing better in Cash Box while others doing better in Billboard—but the most noteworthy example is that of "What Have I Done to Deserve This?" which hit #1 in Cash Box but only #2 in Billboard. Hence, while the Pet Shop Boys are most widely acknowledged as having had only one #1 pop single in the U.S. on account of the Billboard tallies, according to Cash Box they've had two.
