Assorted ramblings from the world of entertainment:• Seventeen years ago this month Dave Grohl played a three-song set on Courthouse Square for the dedication of David Grohl Alley. Grohl's Foo Fighters headline Cleveland's Huntington Bank Stadium, joined by Queens of the Stone Age and Mannequin Pussy. Considering Grohl's Ohio connection, shows in Cleveland by Foo Fighters have been a rarity. For those heading up early, the Rock Hall is planning a Foo Fighters fan day with Foo Fighters' artifacts on display, showings of its past Rock Hall induction performances and Foo Fighters trivia. • Youngstown State University students can be seen in the latest episode of the YouTube series "Cast in Steel."
