Anyone who's spent much time being bombarded by my musical choices knows that two things I really love are Sonny Bono's solo records, as collected on the Rhino Handmade version of Inner Views (I'd avoid the Collector's Choice edition, which is only that album without his other singles), and Beach Boys' Party! So imagine my joy to hear Sonny's peanut butter in the Beach Boys' chocolate! Two great tastes that taste great together!
(Incidentally, you should go here, where the Sonny label is swiped from, to see one of the coolest autograph-collecting strategies I've ever seen)
