"My partner and I searched long and hard for a suitable band to travel to France for our wedding in Morzine. We wanted a small band to keep costs down, but one that packed a punch, that played a wide variety of music and that got everyone on the dance floor. We certainly got that with The Tonics. They were nothing short of BRILLIANT! We requested a trio - Larissa and Barry plus a cajon player (drummer). Everything from the communications pre the big day, to learning my aisle walk song, and the performances on the wedding day itself were perfect. Larissa’s voice was amazing and the musicians were extremely talented. Their sample videos don’t do them justice. We really appreciated their flexibility - they were able to perform a set for the ceremony, a chilled out daytime hour during the drinks reception and then a party set in the evening - they had all bases covered and meant we had fantastic music throughout. They were true professionals but also a lot of fun! All our guests raved about them. Book up now!"

Katy and I just wanted to send you a quick note to thank you both for playing at our wedding. You guys were absolutely incredible. Everyone at the wedding commented on how great you guys were, how good the set was and how you got everyone up and dancing and enjoying themselves. You really got the party started and did everything that we wanted and more. We can’t thank you enough.

Thanks again

- Colin and Katy,, wedding Cornwall
