Oh La La was just perfect. Organising them was effortless; we communicated only via email - and few emails at that - and they delivered exactly what we wanted and exactly what we heard on their website. They sounded fabulous, looked fabulous, were cool friendly and gracious, and very sensitive to changing volume requirements throughout the evening. They did a wonderful job on our special songs, and did equally well with requests from our guests. They even impressed a professional jazz trumpeter, who commented that they were incredibly young to be so good. We were delighted with Oh La La and can't recommend them highly enough.
