Playing adequate tribute to the late, great David Bowie requires a level of funky passion most of us simply cannot achieve in our day-to-day lives. Luckily, EL VY and Stay Human brought that tambourine player in the cowboy hat with them to Colbert last night. That guy plus the laser sounds and ridiculous sax wailing add up to a more-than-worthy version of “Let’s Dance.†So go ahead. Put on your red shoes and dance the blues. That’s why you bought ‘em, isn’t it?
