We are giving away a pair of tickets to see the R&B singer Ciara in New York this Thursday, when she stops here on the Radio Maliboom Boom Tour, sponsored by Malibu Rum. (Recall her fantastic hit “Like A Boy” above; there’s more from her on YouTube, too.) To enter, send an email to firstname.lastname@example.org with the subject line “CIARA ON THURSDAY” before 10 a.m. tomorrow; winners will be notified and told the location of the show before Wednesday at 4 p.m. Please note: Winners must be 21. Good luck!
