Judy Collins, a singer-songwriter who’s been performing for six decades, qualifies as a musical legend.

Legends occasionally come to Annapolis.

To celebrate her 85th birthday, Collins is touring two countries with 24 concerts. Her performance Saturday at Rams Head on Stage is in the middle of the yearlong event.

It’s been a lifetime since she won the Grammy for Best Folk Performance in 1969 for “Both Sides Now,” but it’s not like she’s been standing still since then.

Collins was nominated for Best Folk Album for “Silver Skies Blue” in 2017 and “Spellbound” in 2023, her 55th album and the first exclusively featuring her own songwriting.

She’s also a lifelong civic activist, bringing her celebrity voice to civil rights, landmine abolition and UNICEF. She’s advocated for improving mental health treatment.

Then there was that Best Pop Vocal Performance nomination for “Send in the Clowns” in 1976, from Stephen Sondheim’s play “A Little Night Music.” It’s an earworm, but not one without haters.

Tickets are $75-$95, plus taxes and fees.

Here are some other great things to do in the final week of July. Summer is going fast.

Summer carnival

5 p.m. Thursday

Summer is carnival time, with Tilt-a-Whirls, squirt gun races and cotton candy.

Celebrating bogs

1-3 p.m. Friday

Anne Arundel County has more bogs than any other Maryland county, soft, spongy ground that acts as a natural filter that cleans water seeping into the bay.

To celebrate International Bog Day — I did not make that up — Underwood & Associates, an environmental restoration company, is partnering with the Center for Ecosystem Recovery, Anne Arundel County Bureau of Watershed Protection and the Severn Riverkeeper for a sort of open house at Arden Bog.

Located in Arden on the Severn Park, the free event will include nature hikes, lessons on making your own bog, orchid origami and more. For more information, contact amanda@ecosystemrestoration.com.
