I'll Never Forget Whatshername

Terry, now back home again, looks up some of his old flames. His lack of success with them makes him self-pitying and Bob smug, until suspicion arises that Terry may once have had a drunken fling with Thelma on a coach trip to Blackpool Illuminations. (Note: This episode casts doubt on whether Terry could have been away in the Army in 1967!)
