It's summah time, and even though there are no palm trees or beaches in Denver, when the king of the Hawaiian lulu croons sweet songs like "Blue Hawaii" and "Can't Help Fallin' in Love With You," a romantic night on sandy beach doesn't seem far away. Lannie's Clocktower Cabaret hosts the Elvis impersonator, Jonny Barber (a.k.a. Velvet Elvis), every Thursday night in July. Barber's cool voice and breezy songs help beat the heat and invite us to bask in the season's lighthearted sensations. July 2, 9, 16, 23, 30. 8 p.m. $15. Lannie's Clocktower Cabaret, 1601 Arapahoe St., 303-293-0075
