Communication with Mary was always easy and clear from the beginning. Mary provided me with her song list so we could choose some of our favourites but she was also happy to learn any songs if they were not on our list. We told Mary the songs/artists we like and she tailored a playlist around that specifically for us. Mary has the most amazing voice and really puts her own style into everything she sings and Ben is a great guitarist they make a fabulous team. All our guests commented on the music, I can't wait until we get our wedding video back so I can hear the song I walked down the aisle to again. I couldn't recommend these guys highly enough, nothing is too much trouble for them.

"Mary has an unbelievably beautiful voice. Her and Ben are great vibrant young musicians. She went to great effort in learning a special song for our wedding ceremony. Mary was a great communicator throughout the wedding preps and even gave me some singing lessons so I could sing at our reception. Thank you Mary. We would highly recommend you!"

Wedding Client

"I just wanted to say a HUGE thank you to you and your incredible band for performing on a our wedding day. You are so extremely talented with the most stunning voice and all our fav songs that made the whole process so easy and relaxed. You created the exact vibe we were hoping for, from the amazing acoustic performance during the ceremony to the incredible party vibe of the reception. We thoroughly enjoyed having your sax player weave through the dance floor and the energy you guys brought throughout the entire day that had everyone up and dancing. We received so many compliments from our guests and would recommend you to anyone looking for a band for their event. The only regret we have from the day is not having you guys perform for longer!!"

"I would like to thank Mary & Ben for playing at my recent 50th Birthday Party. They were sensational. The guests were also very complimentary of their performance. It is not often we have an experience more than once. We'd had the privilege of listening to them at a previous function & were so impressed we hired the duo for my party. Thank you both for performing & for being such an important addition to my celebration.  Fabulous family, gorgeous friends, excellent pizza & live entertainment - oh what a night!"

MCM did the Booktopia Christmas party and it went OFF! The band were great - professional, played crowd-pleasers and built up the mood of the night from a chilled start set through to a big bang 2nd half. Everyone loved them and didn’t want it to end!

Thanks for making our event a success!


Booktopia Corporate Client

The Australian Water Association had The Mary Cowell Duo perform at their NSW Awards Gala Dinner at the Hilton with over 360 guests. Mary was an absolute delight to work both in the lead up to the Event and on the night. We had incredibly positive feedback about the duo from our guests who felt the duo provided the perfect mix of background music so that they were able to network with other guests and also provided energy and life to the event. Thank you Mary, looking forward to working with you again!
