update: As fast as sellouts continue to mount for Billy Joel and Elton John 's latest co-headlining run, the two continue to tack additional shows to their itinerary.
The latest additions comprise new nights in both Boston and Philadelphia, where Joel and John are now scheduled to play a total of five and six nights, respectively. Tickets for both new shows hit the box office on Saturday (12/15)
Stops in additional cities are expected, according to a tour spokesperson.
Joel's most recent releases are two albums that simultaneously surfaced in October. The first, "Fantasies & Delusions: Music for Solo Piano" (Columbia/Sony Classical), features pianist Richard Joo performing ten of Joel's original piano compositions. The second, "Essential Billy Joel" (Columbia), is a two-disc set that houses 36 of the musician's previously released pop hits and two classical compositions.
John, meanwhile, is touring in support of this year's "Songs from the West Coast" (Rocket/Universal). The musician wrapped up a series of U.S. solo dates earlier this week.
