SPRINGFIELD — Even though he is only 25 years old, Mo Pitney's singing style is in perfect harmony with country music's giants.Three-time Grammy Award winner Linda Davis recently called him "the current Alan Jackson, the current George Strait."Pitney sings about what is dear to him — faith, family and patriotism. He focuses on his love of the outdoors, too."I definitely love all those things," Pitney said during a recent telephone interview with the Effingham Herald.Along with Davis and Billy Dean, Pitney is set to appear in the "Heart Behind the Music: Songwriter Showcase" at the Mars Theatre on Aug. 17. Pitney's musical preferences are in tune with Davis and Dean's even though he is their junior by 30 years.
