Lead vocalist Heidi Newfield is leaving the band to pursue a solo career next year Ira Dean and Keith Burns have been auditioning singers to replace her, and their choice is expected to be Aubrey Collins, a singer-songwriter originally from Littleton, Colo. Trick Pony got its start 10 years ago at the Wildhorse and landed a Warner Bros. record deal there. The trio’s one Top 10 hit, “On a Night Like This,” was released in 2001.
