Don Raisin, who's worked with Cardinal team mascot Fredbird since 1985, said one of his prized possessions is a ball autographed by Musial, Enos Slaughter and Terry Moore, who played in the outfield together.
"It was always exciting when you knew he was going to be at the ballpark," Raisin said. "It's not going to be the same on opening day."
Rope lines steered mourners toward the casket in a corner of the church.
Myron Schumacher, 71, noted that he was born in 1941, the year Musial broke into the big leagues, and was at the original Busch Stadium in 1963 for Musial's final game.
"He was amazing," Schumacher said.
Retired car salesman Bill Sanders, 64, was like many fans, as taken with Musial's good-natured ways as his considerable baseball prowess. Sanders noted that not once in a 22-year career did Musial get tossed out of a game.
"All of his statistics were absolutely staggering, plus he was a true gentleman," Sanders said. "He even liked the umpires."
Certainly his baseball accomplishments were plentiful: a .331 lifetime average, 475 homers and 3,630 career hits (1,815 at home and an equal number on the road). He helped the Cardinals to three World Series championships in the 1940s and another after his playing days ended — he was general manager of the 1967 team that beat the Red Sox in seven games.
The GM job was short-lived, but Musial was a frequent figure at Busch Stadium, showing up for most opening days and many postseason games, sometimes playing the harmonica, always striking a pose of that unusual, corkscrew left-handed batting stance.
Though in ill health, Musial always perked up when he got to Busch Stadium. He smiled and waved during his last public appearance, a parade lap of the warning track before Game 4 of the NL championship series last fall.
"His fans always did give him energy," Schwarze said. "He could turn it on."
Even near death, the harmonica Musial learned to play while passing the time on long train trips during his career was another source of energy.
"He was playing the week before he passed — a lot better than I've ever played it," Schwarze said.
Did he still play the "Wabash Cannonball?" ''Yes, absolutely," Schwarze added. "He always said he knew more songs but I think he knew about six songs on the harmonica and had about six jokes."
"The No. 6 really goes through his whole life."
