KJ has of course mentioned the machine in his weekly emails.
And today's Q7 looks very interesting:
7. What unusual distinction is shared by these songs? Badfinger's "Without You," The Band's "Sleeping," Cameo's "Word Up," Exile's "Kiss You All Over," Jefferson Airplane's "Somebody to Love," Michael Jackson's "Don't Stop 'Til You Get Enough," Cyndi Lauper's "Time After Time," The Pixies' "Here Comes Your Man," Restless Heart's "The Bluest Eyes in Texas," Roxy Music's "More Than This."
No idea yet, although perhaps it's significant that he includes Badfinger's original, non-hit version of "Without You" instead of Nilsson's chart-topper. Then again perhaps not.
p.s. the latter is yet another shocking omission from the Dave-era Db that I've run across today.
