Paul McCartney was only a teenager when he wrote "When I'm Sixty-Four" for monumental 1967 release "Sgt. Pepper's Lonely Hearts Club Band." Last year the former Beatle turned 64, and his grasp of melody remains supreme, the elasticity of his voice stunning. The impossibly simple "Dance Tonight," a relaxed pop song from new solo album "Memory Almost Full," features a carefree mandolin and long, nostalgic guitar notes. Also released to triple-A is the equally cheerful, but more personal "Ever Present Past," which reaches deeper, sending the lines "searching for the time that has gone so fast" over a bouncy vintage-rock groove that conjures McCartney's rich musical past. Let's hope there is a song sitting in his drawer with the title "When I'm Eighty-Five." —Sven Philipp
