In celebration of the 40th anniversary of the 1967 "Summer of Love," the Turtles, Felix Cavaliere's Rascals and the Zombies have signed on to headline the second annual Hippiefest, starting July 25 at the Molson Amphitheatre in Toronto.

The traveling 21-date trek, which wraps Aug. 21 at Humphrey's Concerts By the Sea in San Diego, will also feature performances from Mountain Mitch Ryder, Badfinger, Country Joe McDonald, Iron Butterfly, Denny Laine and Melanie -- some of which performed at the 1967 Monterey Pop Festival and 1969 Woodstock.

The tour primarily visits theaters, amphitheaters and casinos. Ticket prices range from $25 to $75.

Hippiefest is produced by Toby Ludwig and Ron Hausfeld of Flower Power Concerts, Inc.
