After the "Vega-Tables" session, McCartney performed his song "She's Leaving Home" on piano for Wilson and his wife. Wilson said: "We both just cried. It was beautiful." He performed "Wonderful" on piano for McCartney. Beatles roadie Mal Evans wrote about singing the traditional "On Top of Old Smokey" with McCartney and Wilson, but was not impressed by Wilson's avant-garde attitude to music: "Brian then put a damper on the spontaneity of the whole affair by walking in with a tray of water-filled glasses, trying to arrange it into some sort of session." In a January 1968 interview, Wilson stated of the McCartney episode that "it was a little uptight and we really didn't seem to hit it off. It didn't really flow. ... It didn't really go too good."
