Lounging shirtless at the Soho Beach House on Thursday, Harry – who recently split with girlfriend Cressida Bonas – soaked up the sun after a late night out to celebrate a friend's bachelor party.
By Friday at noon, the prince was in Memphis to visit The King – Harry, 29, and William, 31, took a private tour of Elvis Presley's home, Graceland, along with the rest of the wedding party.
The group spent an hour and a half touring the estate, many of the guests wearing gold Elvis glasses, PEOPLE has learned.
Presley's home was turned into a museum after his death in 1977, and in addition to getting to see the singer's fabled Jungle Room, it's likely the princes checked out some of the flamboyant outfits the King wore on stage before being taken to his grave in the grounds of the estate.
William and Harry are in Memphis to attend the wedding of their close friend Guy Pelly, who is marrying hotel heiress Lizzy Wilson this weekend, and kicked off their visit with a pre-wedding party at Rendezvous, one of the city's most famous barbecue restaurants. Following their Graceland tour, the group headed to the Memphis Country Club for the rehearsal dinner, where they were spotted enjoying cocktails on the venue's rear patio.
So happy Prince William, Prince Harry and the wedding group had a good time on their tour of Graceland.— Priscilla Presley (@Cilla_Presley) May 2, 2014
