The folks at Middlesex Community College threw a party for more than 500 people at Lowell Memorial Auditorium last night with the best music that could be ordered up, All-Beatles-All-the-Time. On stage was the top Beatles tribute band in this part of the country, Beatlejuice, whose players served up note-perfect versions of songs that are the classical music of the past 50 years. The LMA was set up like a music club with a large dance area in front of the stage, round tables on the floor, and additional seating in the mezz level. The audience ranged from kids and lots of college students to a large contingent from the Veterans of Band Battles of the ’60s. If Sgt. Pepper is the Guy Lombardo of the Baby Boomers, we’ll take him. Roll up for the Mystery Tour, and bring on Billy Shears. What creative leaps from “Love Me Do” to “I Am the Walrus” to “Paperback Writer.” Kudos to LMA and MCC for giving us three hours of fun and music, and nothing but fun and music (with a nod to Max Yasgur).
