BOSTON -- It's a sign that the holiday season is fast approaching.

Tickets for the Boston Holiday Pops go on sale Monday. Boston Pops Conductor Keith Lockhart and Santa Claus will greet patrons waiting in line.

The ticket office opens at 8 a.m.

Get there early. In years past, the line has begun forming early in the morning outside Symphony Hall, and stretched around the building by the time the box office opens.
