ESPN senior baseball writer Peter Gammons is in Chicago for the Hot Stove Cool Music charity event, which features Pearl Jam lead singer Eddie Vedder.
Gammons teamed up with Cubs president Theo Epstein for the charity event, which helped underprivileged kids attend baseball games in Boston and Chicago.
While the ESPN writer was in Chicago on Wednesday, Gammons went to the Cubs game as a fan and not as a reporter.
The 70-year-old Boston native sang the seventh inning stretch at Wrigley Field after talking with WGN commentator Len Kasper about the charity event.
The Hot Stove Music event is on Thursday at the Metro.
